Code uses an Arduino Uno to control a slide scanner and a DSLR to make it easier to digitize slides.

I got these relays on Amazon for about $3 each.  They take 5VDC, Gnd, and a low 
voltage to close the normally open relay.  http://www.amazon.com/gp/product/B00G9TQH8U

Features: 
This relay module is 5V active low. 
It is a 1-channel relay interface board, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc.  
It is also able to control various appliances and other equipments with large current.
