Sound Alarm

Here's my second Arduino project, a configurable sound detection alarm that turns on a string of LEDs via sending IR remote commands:

Pretty sweet! Nice setup.

Zippy314,

Very cool. My wife could use something like that in her classroom to control the noise. But I wonder if it wouldn't cause more of a competition to see who could trigger it first!

Do you code the IR or is it just a simple on/off? I wonder if i could jam it, or trigger it, with a TV remote?

How about an IR floodlight for night vision security cameras?

Hey Pat,

The IR remote has a bunch of different codes for different effects. To get the flashing, I had to send the "On" code and then another code that does the flashing. But it would have been pretty easy to send different codes for different flash patterns etc... The codes in this case are NEC, so I'm guessing it depends on the TV remote, but certainly an enterprising student could use one of those universal remotes to learn the codes and then send them...

Excellent project!! Congratulations

Thanks!
