Universal TV sleep timer project
|
|
This TV-Go-Sleep timer turns off any TV after a preset delay time. This project is built around an Arduino microcontroller that uses an open source TV-B-Gone library. The hardware part consists of a pushbutton switch to set the delay time, which is shown on a 7-segment display. When the timer expires, the Arduino transmits “Turn OFF” codes for all known TVs through IR LED, and the TV shuts down.
