Let’s finish up the 3 part series! In this final episode, we’ll write some basic code, build a simple circuit and see how it goes! It’s a simple build, and honestly, fairly useless. The point of it is to show how to gather input values, and create output values to control something.
In this case, we’ll take the position of a potentiometer (knob) and translate it’s value to a speed. Next we’ll use that speed to control how fast an LED is blinking.
Check out the video to see how it all works!
