This circuit jams most IR remote signals.the circuit releases a flood of pulsing IR light that confuses the receiver by corrupting the data stream. this device can be used to jam TV remote control here an IC555 is used to produce a frequency near to 38KHz. this is the frequency at which most of the modern TVs receive the IR beam its required to adjust the 10k potentiometer to adjust the frequency. This can be done through trial and error until the remote no longer responds
