I’m new to Arduino but not that new to electronics, electricity and coding, so I’ve started myself off on a bit of an ambitious project. I ordered the following product on DealExtreme:
I was under the impression that this was an H-bridge circuit that could allow me to control on/off and motor direction of a DC motor. My motor draws 12V, so I have an external voltage source but I cannot figure out the wiring for this module. I am assuming that VCC and GND are for the external power but have no clue as to what A-IB and A-IA could be!
