I have a sainsmart 2 witch mechanical relay that i am trying to connect to the brewpi spark (http://www.amazon.com/gp/product/B0057OC6D8/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1). I am currently trying to figure out how to connect it to the digital output. My current understanding is that the negative wires from the digital out should connect to the IN1 and IN2 pins, while the positive out should connect to the VCC pin. Is this correct? Secondly, since there is only one VCC pin, should I connect the two positive wires from the digital outs to one another and then make a single connection to the VCC pin from both of the two digital outs?
thanks,
