42 Make: Robotic Arms
WHAT ARE WE BUILDING?
Now that we have updated our robotic arm to be controlled by push-buttons,
can we control our robotic arm using potentiometers as well? No problem!
In the same way we altered our original push-button sketch to accommodate
the extra motor, we can use our previous potentiometer software to adapt
the code to our new setup. First, however, we need to build our circuit.
