Question

What is the use of the OUT1 and OUT2 pins?

(a) Input

(b) Output

(c) Activation

(d) Power input

I had been asked this question during an interview.

My doubt stems from Motor Driver (L293D) and Motors in portion Interfacing of Sensors, Actuators, and Other Modules of Arduino

Answer 1

Right choice is (b) Output

To elaborate: The OUT1 and OUT2 pins are used to control the motors that are connected to the IC. They accept up to 5V usually if the module has a 5V rating.
