TV-GO-Sleep – timer that turns off any TV

Most of you have wished that you had a remote control that could be set to turn off your hotel TV after a pre-determined amount of time. The TV-GO-sleep timer exactly does that. The timer is built around an Arduino microcontroller, and hence can also be used to make your own modifications at any time. A simple push button is used to set the timer, which is displayed on a single seven-segment display. When the timer expires, the Arduino uses infrared LED’s  to transmit all the ‘off codes’ it knows, and the TV shuts down.

The project is easy to make and all the required parts are easily available online or any local hobby shop.  The project just requires an Arduino, some resistors, a circuit board and 3- infrared led’s along with a box which is used for mounting the remote. Initially the timer will display 9 which is equal to timer of approximately 90 minutes. On every push button interrupt, the timer decreased by approximately 10 minutes.
