Infrared Remote  | Working principles |  Testing and the common faults  |

Infrared remote emits infrared rays of different wave length for each button we press . For each button wave length will be different  but unique for each button . This is how receiver identifies the button pressed in the remote through the wave length received . These infrared rays we cannot see by our eyes . But our mobile camera can see this . So we can easily check our IR remote through our mobile phones . Common faults that  occur in our remote are due to crystal and battery .
