/*
 * Sketch containing firmware for the ACME Trebes
 * optical printer with an existing Nanolab modification.
 * 
 * Uses an Arduino Uno compatible board, a Sainsmart 
 * 8 relay module board and an ON/OFF toggle switch.
 * Each relay is wired into a momentary switch in 
 * the Nanolab modification box.
