I would like to build (and operate) an electronic circuit to turn on an electrical device remotely. I will be using a speaker output from a Radioshack remote monitor.
The remote device should only turn on after the local sound button has been depressed continuosly for 1second or less than 10 second. I also need to indicate remote operation by means of an LED, but the remote device has to turn off automatically after 10 minutes.
