-/* Pd_Input
- * ------------------
- *
- * This program reads all of the Analog and 12 Digital Inputs
- * and sends the data to the computer as fast as possible.
- * It reads one analog pin and two digital pins per cycle
- * so that the time between reads on all pins remains
- * constant.
- *
- * It was designed to work with the Pd patch of the same
- * name in: Help -> Browser -> examples -> hardware

-/*
- * CAUTION!! Do not turn on the Serial Monitor, it could freeze
- * your computer with this firmware running! It outputs data
- * without a delay() so its very fast.
