In this video, Zahraa demonstrates how to use Arduino to control three separate digital interfaces by writing a program using the Arduino software IDE to turn on each LED separately for a certain time, and using and monitoring it using the serial monitor.
- [Instructor] Alright, so now for the coding.…The very first thing that we need to do…is to initialize the variables.…So I'll go ahead and add it outside the void setup function.…So I'll initialize integer GreenLed…that's connected to pin 10.…And I'll do the same for the other LEDs.…Okay, so the second thing is that I need to set…each LED to be as an output.…So we do so by going to the void setup function.…
And then I use pinMode and then I write down…the same name that I initialized for the variable,…which is GreenLed.…Make sure that you give the same name.…And then as output.…So, I'll do the same thing for the other two LEDs.…So I'll copy the same function.…And in order to make sure that I give the right name…I'll just copy the name from the top.…So this is for the yellow.…
And then finally for the red.…So one of the things that we usually do…in such examples is that we want to make sure…that the LEDs are off to start with.…So to do, we initialize the digital write…inside the void setup.…So digitalWrite for the green LED to be off,…
