Powering Arduino Uno ON/OFF with IR

Using Arduino Project Guidance
#1

Can I power the Arduino on and off using IR? Is this possible? I have looked around and see how I can change lights, but I would like to be able to turn the board on/off using my remote. Just some clarity on this would be awesome. Thanks!

#2

Use the sleep library to put the UNO to sleep and enable external interrupts.
Use an IR photo-diode (like the Vishay TSOP series) to trigger the interrupt.

#3

PSUEDO CODE:

Main loop()
Usual functioning, like decoding IR signals and dealing with the corresponding I/O
if IR signal = "Turn me off"...
sleep(enable interrupts);

An issue will be how quickly the UNO can recover from sleep once the interrupt is triggered and then process the IR code to see if it is a "wake up" signal and enable the main loop or just go back to sleep (if it wasn't a wake up code).

Thanks a lot guys. With your help I was sent in the right direction and got everything working. Thanks!
