Now for the serial output lab:

An Arduino with a potentiometer in front of a monitor displaying its output

Worked great, no issues. I got lazy and skipped the breadboard since the pot can plug right in to power / ground / analog without any additional components. I tweaked the Processing code to print a longer (wider) history of the output, and to draw the signal in a nostalgic shade of oscilloscope-green.

This is going to be very handy… it already went to good use when Arturo and I wanted to see what the output from some FSRs would look like in the context of our media controller project.
