I'm just starting my first Arduino project and have done some research but can't find an answer to this question. I'm also fairly new to electronics in general.
I want to control a door strike with an Arduino (an Uno R3 for now). The door strike needs a 12V power source and draws 200mA. I have a 12V power supply that provides 1.5A (my multimeter measures 12.2V from it).
It is my understanding that the Arduino can be powered by a 12V source via the Vin pin. Will it therefore be a simple matter to use the same power source for the arduino and the strike? Am I better off using some sort of voltage converter to power the Arduino? Will there be any issue with sudden changes in voltage when the strike is activated?
