What happens when the sequence 0 1 1 is fed to the IN1, IN2 and EN1_2 pins respectively?

(a) Clockwise Motor Rotation

(b) Anticlockwise Motor Rotation

(c) Stops Motor Rotation

(d) Stalls Motor Rotation

I had been asked this question at a job interview.

Enquiry is from Motor Driver (L293D) and Motors topic in section Interfacing of Sensors, Actuators, and Other Modules of Arduino

Best answer
The correct choice is (b) Anticlockwise Motor Rotation

Explanation: Anticlockwise motor rotation  gives the correct logic sequence which enables the micro-controller to turn one set of motors anticlockwise. This is true for the other set too.
