Have you ever wondered how all this electronic stuff that surrounds us every day is actually programmed? Things like your toaster or your microwave or your fridge or whatever electronic widget you might be using. It all has code and electronics behind it. Well, in this lesson, we're gonna walk through the code that powers this simple turn timer, we're gonna be using a micro controller development board called Arduino. Arduinos are like really small computers that are fantastic for helping you build electronics projects. This will be your chance to throw your brain at some code and see how something like this simple turn timer is actually programed. We're gonna be talking generally about how an Arduino sketch is laid out. So even if maybe some of the code seems a bit confusing to you, I think you're gonna get a gist for how a program can be organized. We'll make sure to link to the code in the description. Now hey, before we start, if you haven't yet, please do subscribe to our channel. It costs you nothing, but it really helps us deliver great content. Also, if you have any questions as we go through this code about Arduino or the code that I'm writing, please feel free to ask it. Or if you've got some advice on how I can better write the code, please add that too, I know I am far from perfect. It's always a little bit scary throwing my code out there because I know how much experience people have in comparison to me, but, hey, as they say, what you fear most is what you most need to do. So, all right, let's go ahead and jump into this code. So let's start with the general layout of an Arduino program, and I'm gonna open up a brand new sketch just to show this. So when you open up a new sketch in your Arduino IDE, there's two functions that get prefilled for you. One is set up and one is loop. All the code in setup runs first, and it only runs once. And then all the code in the loop, it runs from the top. It goes down executes code. And when it gets to the bottom, it starts over again. So it loops over and over. So in the turn timer program, we're gonna have a setup and we're gonna have a loop just like we do in every other Arduino program.

As a coder I really enjoyed this explanation. It's always good to see what other people are doing

[ChadKapper]

Your tutorials are the best! You present everything in a way that makes it so much easier to learn than other channels.

Thank you 🙏

This was really a great overview of a slightly more complicated project. It will be really helpful for people taking the step between a simple example and an actual project that meets their needs. That step can be daunting for some but you have done a wonderful job of explaining it. Thank you for sharing your knowledge.

Thank you for doing this videos. I find that ur best arduino teacher Iwe seen on youtube

[danthemann]

Excellent discussion, keep up the good work.

Great video. Thank you! I wish there were more actual fastLED tutorials available. Every one shows what they've done leaving out how it's done. LEDs and Arduino are like PB & J. Meant to work together. All of my projects incorporate LEDs in them similar to your lesson here. The fastLED library is amazing and there's so much more in there than just blink and rainbow. 😉

You are a great teacher . I learned a lot from you . On my BD will invest in your amazing course . Cant wait . peace

Creative video, thanks for sharing :)

Many thanks for another useful video. I was interested in building the device. Can you advise when to source the hardware - translucent box, switch, LED, s etc?

Many thanks
Roger

I was expecting you to explain the use of the pointy brackets.. but you sidestepped it.
