So I bought this motorcontroller: http://www.pololu.com/catalog/product/713/resources and I plan to use it with a picaxe 18 M2.
I powered the entire system with a 9V battery, I made all the connections needed, including a led indicator that is connected to the positive terminal of the 9V battery, and I also have put a 5V regulator for the picaxe chip. The problem I have is that when I connect the "vmot" to the 9V positive terminal, the led turns off and when I check the voltage between "vmot" and the ground, my multimeter shows 0 V.
I'm not sure, but I think this is happening because of the battery, maybe I should have put 4 AA batteries. If not, what did I do wrong?
