    My Arduino would control a solenoid. How would I go about powering my Arduino and the solenoid. The solenoid is a 12 V solenoid. It would only need to be open momentarily, so the voltage would only need to be applied momentarily.I would need some sort of rechargeable battery right? In if I didn't have a battery, how would I power both? How would you go about this?

    Should I go the transistor route to power the solenoid? In normal circuits I see people build, they have the solenoid powered by a separate power source (like a 9V) while the arduino is plugged in via USB. But I can't do this in my situation. What should I do? How will I power this? A battery and a solar panel?

    it all depends where you are going to have it. if its outdoors then maybe a solor panel but if its indoors than you should power it with a battery or maybe an ac adapter.
