I buy a WIFI camera that I want to use on a remote controlled car. Of course the car will be driven by an Arduino (Uno) !
The camera is powered by a simple micro USB wire. So 5V DC.
I think it will consume quite a lot of energy so I would like to turn it off sometime (when I don't use the car for instance).
It is my first project so I would like to know how you would do that. I plan to use a Relay as a switch between the 5V output of the arduino & the camera +, camera GND is linked to arduino GND. Is that good ?
