how to detect when a small motor is powered

Post by multinet » Sunday 01 April 2018 12:45

Hello

I've a flap with a motor so that only my cat can enter it.

I want to detect when the motor is powered by the flap (when the cat enter or exit)

The motor is powered by 4 batteries of 1,5v so about 6v

Is there a possibility to connect the flap to my gpio so that I can detect when the motor is powered ?

Thank you
