Hi, I picked one of these of eBay while i am waiting for the 2.5 amp controller from the store. I was able to get it to work. It move forward backward and both left and right. It would not stop with the with the HBridge control. The control would allow me to change directions. I added a PWM control which i could make it move and stop and different speeds. I added the voice command and noticed when i said stop the robot would turn. Anyway i was just playing with it moving around the room and it just stop. It looks like one of the digital ports stop working. Verified by attaching a server to it. Before i do anything else i want to double check my setup.
On the attached picture i have +5 to +5 on the board have the gnd to gnd on the board. The DIR1 I have it going to d16 the DIR2 going to D17 I have both PWM1 and PWM2 tied together and set to D1. Which wen i move the slider it would speed up and down and when i clicked stop it would stop.
Question DIR1 stand for?
Question on the H bridge controller I was only using Left TriggerA(D16) and B(17). What is the Right trigger A and B for. What do they mean in terms of controls to the motors?
Since i did blow out D15 i want to make sure what i doing is right.
If i wanted to fix the D15 what would i need to change on the board?
