i am cuurently doing a project on making a line follower using l293d ic and arduino.here's the problem.
i connected the two enable pins to pwm pins in arduino and uiploaded th code to drive both motors forward. But even without connecting power for motor to ic , the motors start turning. i dont know why this happens .but when i remove the enable pins it runs on the power(9v) for motor and i am not able to control speed.I WANT TO RUN THE MOTORS ON SEPARATE POWER(9V) other than the enable but still be able to control their speeds.please help me out...
thanks for your help
