+/**
+ * This is a specialized version of the mcopy firmware for
+ * controlling the JK104-R/Bolex camera of the optical printer 
+ * at MONO NO AWARE. This uses a Sainsmart 8 Solid State Relay 
+ * board wired into the directional switches of a JK104-R/Bolex camera 
+ * controller box, a secondary projector controller box and it 
+ * runs on an Arduino Uno compatible board.
+ * 
+ * Pins 
+ * 12 - CH1 - BWD CAM 1
+ * 11 - CH2 - FWD CAM 1 (bridged to CH1)
+ * 10 - CH3 - BWD CAM 1
+ * 09 - CH4 - FWD CAM 1  (bridged to CH3)
+ * 08 - CH5 - BWD CAM 1
+ *  - controls the directional relays of the Bolex Camera.
+ * 07 - CH8 - 4 pronged trigger cable
+ *  - triggers the camera
