i am working on a four motor chassis project and use two l293d motor drivers IC's. I have used them before, without any problems and checks everything is hook up correctly.
The problem seems to be when I switch the motor driver from forward direction to reverse direction, I am getting a high current/voltage dip which is resetting the Arduino. I was wondering if any one else has experienced the same problem and how to fix it.
I need to review the circuit, may be switching the motor is causing a temporary short and this is resetting the complete board. So adding some didoes in-line with the motors would eliminate this condition.
Also how can I test the current/voltage during this motor switch condition, would a scope on the supply pins show the dip in voltage?
