TV remote control is a commonly used device in our everyday life. Would you like to surprise your family members or friends by making this fun circuit namely “TV remote jammer circuit“? Yes you can use this circuit to stop the working of your TV remote and nobody would have a clue about why that stopped working. This project we have designed is a simple circuit, which blocks the communication established between TV and remote control. (Also check this IR remote control tester circuit)
The communication between TV and remote control is IR (Infra Red) communication. So basically this circuit is a IR jammer circuit. As shown in below image the remote consists of an IR (Infrared) LED, which blinks every time a button is pressed.
The TV consists of an IR receiver which receives these blinking pulses and decodes them for appropriate response. These IR pulses by remote control can not be detected by human eye. These pulses can be captured by a camera, as camera can pick up these pulses.
As shown in figure, the IR communication established between TV and remote uses a wave length just above visible RED color.
