The sound square idea is what im after in a sense however im looking to place this over a computer screen
what im struggling with is what i need to wire the LED receivers to.
not sure if the arduino will be powerful enough for it
so ALL LED's are lit
where when they wave over the IR Receiver and emitter an LED flashes on.
To turn the screen on as in "wake it up".
Do you mean the power to this monitor, or do you mean to blank the display?
