Measure the juice left in your AA or AAA batteries anytime using an Arduino Uno and a couple of jumpers.

This library controls and drives motion of all types of bipolar stepper motors with 2 phase (4 terminals).

This library creates an 8-bit IO port for Arduino by combining any 8 Arduino pins. With this library, one can send/get direct 8-bit data.
