Arduino Made Easy(er) The Welding Sketch - Lesson 08 - Duration: 34:45.

welcome to another episode of Arduino Made Easy this is lesson 8 and we're

going to go over the welder scene that I did on a previous video so let's see how

we did that I'm Tom Kvichakc and this is Toms Trains and Things this channel was

created to help other modelers who are need of guidance in pursuing their dream

of building a model railroad we're going to put some animation in our model

railroad today with this sketch of an arc welder and some building lights and

I showed you in a previous video how I did that now I'm not going to take it

apart and put it together because that's going to take a long time because we got

seven LEDs on there and we have a sensor now this sensor is the same sensor that

I used for the gate crossing it's a IR sensor I'm gonna plug this in so you

could see what this actually looks like

will actuate it and you'll see the four LEDs come on right here and once those

four LEDs come on then the arc welder will come on now well how I have it and

the sketch it'll go through the cycle three times and then it'll then it'll

stop so that's two times right there and it'll go through there one more time and

it'll shut off by itself you could set this for how long you want it to stay on

you could set it for how short you don't even have to have this sensor on here to

even start it up you could do it without the sensor and have it come on

automatically as soon as you apply power to it so I just wanted you to see the

the sequence of events on here I have all these set at a two-second delay if

you would like to see more videos like this go ahead and hit that subscribe

button and while you're at it doing that also you could be notified whenever I

have a new video coming out check out my playlist on the playlist page I have a

lot of playlists on there that are categorized for easy discovery so check

that out now let's get started with this sketch

right now so let's go over to here now you can see I have a few notes up here I

have this adapted for the the pro mini because that's what I have on my layout

simulates an arc welder and other Lighting's in the scene building lights

are seven eight ten and eleven and arc welder is pins two three and four where

pin three is a pwm pin that's because we're using an analog right to the glow

pin so let's start typing in here now we have the four LEDs for the building so

we're going to start with that and let me do it this way here all right so we

got integer any it's oh yeah that's awesome ledB1 equals seven Mt we

need db2 equal 8 TB three equal nine and tdb4 equal seven eight nine ten no I got

sony 10 11 excuse me so we're gonna do it that way 7 8 10 11

I saved 5 6 5 6 & 9 those are the other pwm pins on a pro mini for a future

project I'm going to do something else on that later so I left those pins empty

for right now we're gonna do 2 3 pins for the arc welder now so int LED weight

is on pin 2 integer tell me d WP is on 3 n OT MP d DW e is

on pin for those are the photos are all the LEDs now we're going into the sensor

and the information that we're going to need

the if statement so the first first one for is the sensor that we're going to

use and we'll call that sensor one and we have that on a one now we're gonna

use a something that we did in the gate crossing we're gonna use sequence

started and we'll start that off with a as a zero we're gonna do a wait and this

is for the delay between the building lights and we're gonna start that off

with that 1000 milliseconds which is one second and then we'll have another

variable in here cont and we'll count equal three now this weld count 3 you

could change that to whatever you want if you want your welder to stay on

longer than three cycles through the procedure then you could change this

number right here on the well count I kept it down low on this demonstration

so it wouldn't take that long you could see it go through the entire process and

also shut off so I left it at 3 okay the next thing we're gonna do is we're gonna

do the pin modes okay I'm going to copy a little bit here sensor was an input

and we need one and what I'm going to do is copy this several times

I'll be two three and four so I just changed the number on unit two three and

four now I'll do it a couple more times we're

just gonna have to change it to white blue and glow cane okay so control beam

okay so LED white blue and last one we just call glow pin now we have all that

set up right there we're gonna go into the loop so we could see what's going on

with that and we're going to just put three procedures in there for right now

we're gonna create that we're going to put the procedures in here now in the

loop and then create the procedures and then write what we need to activate the

procedures so the first one is going to be the building lights being like LD ing

missing this oops Capitol building lights okay we'll come down a couple and

we'll call the next one welder and the next one

okay so those are the three procedures we're going to do in there now like I

showed you in a previous lesson we did we wrote what those procedures are

outside of the loop so we'll go down below the loop and then we'll create

those three procedures in here the first procedure we're going to do is the

building light so let's start with this we'll do Boyd Boyd building lights and

then we'll come down we'll do our curly braces and bring that down a few we're

going to do an if statement in there and we're going to test the see if the LED

b1 is on or off okay and we're gonna say if digital read LED 1 b1 is low that

means it's off and digital read glow pin is low that means that's off then we'll

run this procedure if those if either part of that is false say like if the

LED is already on we don't need to run the procedure so it'll just skip the

procedure with the if statement so if and we'll have to do it at two of those

tal or digital read LED b1 is low put another parenthesis in there and

Digital Read

glow pin is low

then it's okay to start this procedure so we have to put some curly braces in

there for this and then we'll put the conditions in there for what we want to

see so it's going to be digital right

LED before it's high and then we're going to put the delay in there right

now and we're just going to say 2 seconds so we're going to times 2 since

the delay is 1 second 1000 milliseconds now we're going to do the same thing

with all the rest of them so I'm just going to copy this right here 3 so we're

gonna start off with 4 then we're going to do 2 3 and 1 that's the way I had it

on my original sketch so 3 & 1 & you could do it in any order that you want

it doesn't have to be this order here whichever order that you want to do it

in but that's how I did it in mind you got the if statement in there if both of

those are off we're going to do whatever it says in these 4 in these commands

right here we're going to turn on all 4 LEDs and we're gonna wait 2 seconds

between each step on there and and at the end we're also going to wait 2

seconds before we do something else void you know de

and then it's put some lines up here so we can see what we're doing and we'll

also put the curly braces in there now so we don't forget them

okay void welder so what we want to do is we want to give it random on and off

in there so with that random on and off we're going to do the count and then

random and then the minimum and then the maximum now these figures could be

changed around we're going to start to count in here so we're going to use a

for statement and we're gonna say integer I equals zero we say I is less

than count

and then I we're going to sequence through it so what we're doing right

there is we're taking the count and we're going to sequence through the

count in between the random numbers that are generated from Arduino between 10

and 60 it's going to give us the on and off for the LEDs curly brace in for that

one for the for statement okay now in the for statement we're going to do a

digital write for the LED white we're going to stay high and we'll have to put

out parentheses and that right there and we're going to put a delay in there a

random delay and we'll say 60 and you could change this then we have to put

two of those in there okay let's move this give us some more room here okay so

we haven't turned it on so now we have to turn it back off so what I'm going to

do is just gonna copy this right here

and I'm going to make this low we're turning it off and going to give this a

different value we're going to keep it off longer than we had it on so we're

giving it 200 okay we're going to do the same thing with the blue so what I'm

going to do is come over here we're going to change this to blue at high and

we're going to give this a delay of 10 we're gonna so it flickers at a

different rate then the and it will copy this so all we have to do is change the

low and stuff okay so come over here blue change this to low and change this

to we'll give this a hundred okay let's move this it's move these things up here

this is now we're going to put another four statement in here for the glow but

we're going to do it differently okay so we're going to do for integer we're

gonna call this one J equal 50 and we could play around with figures on here

to make it look however we want it to look and do greater than one and

J and we're going to we're going to decrease it so we're going to start at

50 and work our way down to one and so after that we need to put in curly

braces for that one okay and then we're going to do a right here analog analog

right on the globe pin

and with the value of J and we're going to delay that about 100 I have to set a

delay for the entire procedure so I'm going to do it you delay random here

also and I'm going to set these to eight hundred and two thousand and then we

have to put two closing braces in there and then that right there okay so there

is the welder now what we have here on the on the welder sketch is okay we have

to count random 10 10 as the minimum and 60 is the the high and then for the

integer zero integer less than count so we're going to take that and we're going

to count up between 10 and 60 at one step at a time for the welder and so in

the digital right for the white we're going to put a delay in there a random

of 60 and that a maximum that's not saying it's definitely 60 when you say

random it's when you have one figure in there that is the maximum figure if you

have two figures in here like that you have the first figure which is minimum

and the second figure which is maximum so that's what we're going to do we're

going to step through the white and turn it on and off at those random random

times right there with these random times so it's not all the same and do

the same thing with the blue but at a different rate than the white and then

on here for the glow pin we're going to turn the

pin on after the white and the blue is finished and it's gonna start up high

and it's going to it's going to start up high and then get dimmer as it goes goes

down to to one from fifty as it counts down from fifty to one it's going to get

dimmer so that's simulating the the glow on the metal when it when they bring the

stick up off of it it's glowing real bright and as time

goes by it'll get dimmer and that's exactly how a welder works come down

here we're gonna do video D and you t do W and I don't think that's how I did it

shut down yeah with an underscore okay so we're gonna work on that right now

and all we have to do with this right here is just shut all the LEDs off so

let's let's just shut the everything off here and so this is another thing where

we're going to put in the curly braces first and then give us some room here so

we don't have to do it at the very bottom of the screen okay so we have our

beginning curly brace so everything that's inside of that will be in the

procedure for setting it down so we're going to have to do a digital right

led and we're just going to start from the beginning the b1 and we'll do a low

and a semicolon and so we're going to do this to all the led so I'm just going to

copy this right here okay two three four and then the three group glue in the

three other pins okay so we'll just change this to two three four and then

led this one will be white

this one will be blue and this one will be glow pin

oh I could put an analogue right on that okay we put an analogue right L ugh

right on to glow pin and we'll give that a value of zero because we're using the

analog values on the glow pin and so now what we have to do is we'll go up here

in the loop and play around with the loop we want to start the loop up and

what we want to do in there is we want to read the sensor 1 we want to read

this sensor right here and we want to also see the sequences like we did with

it with the crossing gate we have a sequence and we're not started yet so we

want to put in an if statement about if this is low now you remember whenever

this whenever it's not covered it's high so whenever you cover it it goes low so

we're going to say whenever we cover that up and the sequence started is zero

the sequence hasn't started yet then we're going to go through this if

statement and what we're going to do in the instance in the if statement is

we're going to say we're going to change the sequence started to true which is a

1 and then we're going to turn on the building lights so let's do that right

here so we'll come up here and we'll write if if yeah let me see on these

when you have to put - oops l digital read of sensor 1 now where we're going

to read the digital read sensor 1 we have to put a parenthesis there

equal oops equal and we want to say low because that is what's happening in in

there at this time whenever we cover it up it's going to

low and where's the end and okay is the qu v NCE

destiny or sequence started oops equal okay

zero zero okay now put two parentheses in there now what's it saying is in here

is whenever we cover up the sensor and I got to change that to a parenthesis okay

we cover up the sensor and if the sensor is covered and sequence started is false

nothing has started yet then we'll go through this statement right here

so what we're going to do is we're going to put in our curly brace but we're

going to put the other one in after here boom right there and we'll come back up

here and before we turn the building lights on we're going to say the equ is

e sequence started equal 1 now what we did there is we changed the state of the

sequence from not working - working so now we're in the sequence and we're

turning on the building lights so that's where we are right now

so what do we want to do after that we don't want to turn the welder on right

now we want to put in an if statement for the welder also so we're going to

have to do the same thing on the welder we're going to have to read the sensor

and when the sensor is high that means we're not over top of the sensor like

that so the sequence and the sequence already started

so whenever the this is not covered and the sequence has already started then

we'll start the welder sequence so we'll write that in like this

if digital right and the digital life it'll read we want to read the sensor

sensor one put a parenthesis in there and if the sensor is high that means

there's nothing over top of the sensor do one of these and okay is the qu ence

sequence started Eagle 1 and I see what I did over here I didn't need that right

there okay now I'm gonna go back there we go

that's it all right now we'll do this again put this in here and we'll put the

other one underneath the welder for the end of it okay but before we get there

we want to increment how many times we want the welder to sequence before we

shut everything down now if you want this thing to stay on you don't have to

put this next line in there if you want yeah once you once you trip it or you

don't even have to have the first if statement in there if you want to have

this on all the time you could just forget about that first if statement and

just put building lights put welder and then not put the shut down the procedure

in there but what I'm doing is in here is I'm turning it on with a sensor so if

somebody walks up to it it'll start going now I'm for this demonstration

only I haven't gone for three times so you know it doesn't have to we don't

have to sit here and watch it for five minutes but anyway we're going to put in

a for statement for the welder and what we're going to say here is four and here

we go with all those parentheses again now this is where it gets tricky okay

we're going to do an integer we're going to call this one X because we already

have an eye and a J and we don't want to confuse it even though the the other

integers I and J are within the procedure itself they're contained

within that procedure and don't go outside that procedure we're going to

call this different anyway just so nothing gets confused here and we're

going to say equal one okay if that's equal to one and

is less than or equal to and you know welder count we're gonna do a welder

count right there semicolon and then X plus plus and then close the parenthesis

and then open up that and put another thing behind the welder another curly

brace for this or behind the welder now this is where it gets tricky because

your your have multiple curly braces in here so you have to make sure that your

curly braces are in the right place so the for statement just has the welder in

there and that's what we want once this second if statement is finished it's

going to step out and go to the next line and that next line is a shutdown so

what we're going to do for that shutdown is we're going to change what the

sequence is so we're gonna say sequence started and we're going to change that

back to zero and put that there and then shutdown and that's it now we're going

to go through this and hopefully I don't have any mistakes in here

and we got to clean this up a little bit so let's see if this thing compiles okay

I'll click on that right there and we'll sit and wait if it's not doing anything

and you don't see any error messages popping up that means it's going through

there and changing it into machine language and there we go it's it's done

it's done compiled so it works so let me plug this thing in and it's already got

the sketch in there but for loop if did

you we'd sensor is low whenever I cover up

that sensor and sequence started equals zero then it'll go through it'll change

sequence started to one and it'll open up the building lights okay and then

when that is finished once the building lights are on and you have that last

two-second delay on there it'll go through this next one if digital read is

high nothing's over top of the sensor and sequence started is true then it'll

go through the welder sequence and the for statement in here where it says it's

counting and weld count is equal to three right here so it'll count it'll go

through that procedure three times and once it goes through that procedure 3

times then it'll drop down over here it'll change sequence started to false

that means nothing's happening and it'll go through the shutdown

procedure so let's walk this through right now

so I'm putting my finger over top of it and the building lights are starting to

come on ok so that's so it's in the building lights once it's finished with

that it comes into here and it counts out three cycles of that procedure so

it'll flash the white and the blue and then it'll the red will decrease it'll

do that three times and then once it does that it'll change the sequence

started to false zero and you know shut everything off just like that

now that's the procedure I have the Fritzing diagram in the beginning I'll

put it in in the end also just because I didn't show you how I hooked all this

thing up at the beginning so you know I'll have the code in there and

everything else in there thank you for watching I'll have another

video up sometime with the df' player I'm going to show you the sketch of the

DAF player that's the next one it's going to be up that's a pretty simple

sketch on there but that I just wanted to show you

how you can get to use that DF player for your sound effects on your layout so

we'll see Ya
