Now, there is a lot to unpack here. That said, despite the

significant increase in length, this most recent version of

our robotic-arm code is nothing more than our last two

examples put together. This newest version of our code will

allow us to accurately control the angles of each one of our

servos through the use of a rotary encoder, allowing us to

select which motor is active at a given time by pressing the

a closer look at how it all works.

First, we have our variables above our void setup. Though we

now have quite a few variabl ...
