Using SN754410 for tank bot -- trouble turning
September 30, 2012
I have wired up a little four motor tank. I'm using the SN754410 chip to drive it--everything works fine, except I can't get the motors on each side to go in opposite directions.
Turn right, only fires left side motors.
Turn left, only the right side motors fire.
What I would like, is if turning right--the left motors go forward and right motors go back. Making a zero point turn.
I'm a hack, and content with it. But, I'm obsessing over this detail.
