I have one of these IC 2262/2272 Wireless controller and receiver. If managed to connect it in such way that the Arduino blinks a LED after a button is pressed, it works fine.
My question is, is it possible to power up the Arduino - allow for power go to it, after I've pressed a button ?
The final product I'm aiming to build is a remote controlled car alarm, that will check for pressure changes and text/call me if such are detected, when armed. Ideally I wouldn't want to have the circuit run constantly as when it's checking only once every 10 seconds for pressure change and tehre's no GSM shield connected yet, it went trough a 2000-2600 mAh (Not original and a bit used so not sure the exact number) portable battery in 20 hours, so letting it run isn't great for my car battery.
I'm pretty sure this question is more for this Stack as I'm asking how to essentially power the Arduino on demand, and not anything else Arduino related.
