TIL about the SparkFun SerIO board. This now-discontinued product is an even-simpler-than-Arduino physical computing device. When connected to a USB port, it appears as a serial device. Send it simple commands at 57600 bps and it will read/write pins for you. For example, this configures Pin 13 as an output, and sets the value high:

> C,13,1
Pin: 13 Input/Output: 1
> W,13,1
Pin: 13 Value: 1

This lights the 'Stat' LED
