A Whimsical Doorbell
October 2005
The use of radio frequency (RF) control for switching devices is becoming increasingly popular. The project described here uses RF control to actuate a zany, whimsical doorbell. The electronics involved in this circuit can be used to control more practical projects, such as a garage door opener, appliance turn-on, wireless home signaling (paging), and remote sensing.
