Hey all, pretty new to all this and am working on a project, so far so good......
My set up is an arduino mega2560 connected to 4 ardumoto drive shields, and a stepper motor, and various buttons 8 off to be precise.
What I am trying to do is run the motors in a set sequence for a set period of time, I can operate pairs of motors in either direction just fine, when I come to operate motors that run on independent drive shields the motor will only ever run in reverse
I have tried numerous things and changing the pins from high to low and vice versa and all it does it effectivley turn the motor off, like I say I am new and been doing this for 3 days and have got no further, can someone tell me what I am doing wrong??
The drive sheilds source power from a 12V 5A dc power supply, the mega is taking power from the usb right now.
Each switch has a 10K resistor on it connected to ground.
Each pair of motors (ie drive1 motors a & b) run just fine backwards or forwards
Problem occurs when introducing a motor from an independant board, in a sequence of three motors one will only work in reverse or "off".
The timings are perfect and the stepper behaves as expected
Changing (dir_e, LOW) makes the motor not run
Changing (pwm_e, LOW) makes the motor not run
The code I am posting is where I am so far
Thanks in advance.
