Arduino IR Blaster
Turns things on so I don’t have to                     


I have an AV system connected to a power strip so that I can turn everything on and off at once.

The problem is that my amplifier doesn’t power up automatically and I need to press the ‘on’ button on the remote every time.

So I bought a programmable Arduino IR reader/blaster, read the IR signals that the remote was sending out, and programmed the remote to send those signals once it received power.

I’ve got the blaster plugged into the same power strip.  I energize the strip, the blaster powers up, waits a few seconds, then sends the ‘on’ signal, and turns up the volume for me, automatically.  It’s great.
