Want to control two motors simultaneously using just 1 IC ? L293D is the most common dual H bridge motor control IC that can drive two motors in both directions. Two PWM pins lets you control the speed of motor from either an Arduino or a micro controller.
The motor operations of two motors can be controlled by input logic at pins 2 & 7 and 10 & 15. Input logic 00 or 11 will stop the corresponding motor. Logic 01 and 10 will rotate it in clockwise and anticlockwise directions, respectively.
