The most valuable part of this example is not its physical part but its logical one, and I'll show you the associated functions to deal with analog outputs and a very important control structure in any programming language called a
for loop in the code we will be using for this circuit.
Dealing with analog outputs from the programming side is just a matter of using the
analogWrite() function, which, as its name implies, writes an analog value through a pin.
It takes two parameters, similar to the
