Introduction
Infrared remote controls have made our life so much better, we have power to control many infrared based devices sitting at one place.
But, our device Infrared Remote Control Jammer is a device which will make you unable to use your power .
How Remote-Controlled Appliances Work
Remote-controlled devices use an invisible infrared link and they can easily be identified by he one or more infrared LEDs .
When you press a button on the remote control, a microprocessor generates a series of binary pulses, which the infrared receiver inside the target appliance attempts to decode into one of several functions.
The frequency of these ones(1) and zeros(0) is sent at a rate of between 38 and 40 kHz from the remote control to the receiver.
Disabling the IR Remote Control Receiver
Confuse the remote control receiver, by sending a non-stop stream of zeros and ones at the frequency range of 38 khz to 40 khz .
But our stream will not contain any information, so the receiver will not be able to sense the input and doesn’t change its state.
Now the remote control signal can not reach to the receiver and cannot create change in the receiver
