Hi,
When I press a button in IR remote, the transmiter transmit modulated signal at 38khz. TSOP1337 recieves it.when receiver receives, a sound will generate in a speaker. If I press for long time,the intensity of sound must change. can u give any idea about this circuit by using Op-amps or 555, transistors,etc with out using micro-controllers.
