WHAT ARE WE BUILDING?
In this project, we will begin by creating a simple rotary-encoder circuit.
Then we will write a quick Arduino sketch to read our rotary-encoder data,
just as we did for our previous methods of input. Thanks to the rotary
encoder’s ability to freely rotate 360 degrees, it’s a useful and accurate
method of input for robotic-arm projects.
Our first step will be wiring the encoder into our robotic-arm circuit.
Thankfully, we can keep all our motor wiring the same and do not need to
disconnect any of our motors. Our first connection will be our CLK pin, which
will be connected to digital pin 12. Next, w ...
