Hi all -
(Wow ... just as a warning for everyone here: COPY YOUR WORK before posting in this forum. I just spent about 1/2 researching and writing a post, only to have it be sacrificed to the database gods on posting.)
I'm not sure where else to post this item. Any help would be greatly appreciated.
I am trying to use this motor driver board:
I've attached a picture of the page with documentation on it if that's easier for you.
I have a 9V battery across the motor driver VCC and GND.
I have verified that I have PWM running at 100% duty cycle on ShieldBase port 6. I have connected this to IA on the motor driver board. I have tried leaving IB disconnected. Tried connecting IB to Shieldbase GND. Tried connecting IB to an unused Shieldbase digital port. Tried IB to a Shieldbase unused analog port.
EXPECTED RESULT: Motor goes ACTUAL RESULT: Nothing
I have tried everything I could think of with no luck. The only think I was successful at was to connect IA directly to the batter GND. RESULT: The motor whined for a second and then the smoke when out of Channel B of my motor driver board.
Any suggestions would be greatly appreciated.
