As the title says, I'm using an SN754410 IC to power a standard DC motor. I've been following these directions: http://web.ics.purdue.edu/~fwinkler/616/sn754410_Arduino.pdf
. By changing the PWM value, I can get voltage across the two outputs to be between 0 and 12V (as measured by a multimeter), but when hooked to the motor it does nothing... The motor will spin when hooked directly to 12V, and I was able to control it via PWM with a TIP31B transistor as well. However, I would like the ability to reverse the direction (thus the SN754410).
I'm at a loss on this one. Any ideas?
