Remote Control Operator
Enhancing remote controlled lighting
Remote controlled light switches are becoming more and more common. DIY stores have inexpensive sets consisting of several light switches and a remote control unit. It's then easy to control everything from your armchair. But how can you control the lighting when you're away, as a deterrent to burglars? With the help of this little circuit that is no longer a problem.
