Working
The circuit consists of an 8051 microcontroller, an IR transmitter, an IR receiver, and a few other components. The microcontroller is programmed to generate the IR signals that are necessary to control the TV. The IR transmitter then sends these signals to the TV. The IR receiver on the TV receives these signals and decodes them, which then performs the desired action.
The microcontroller is programmed to use a specific protocol to generate the IR signals. This protocol defines how the data is encoded into the IR signals. The IR transmitter then uses this protocol to modulate the IR signals. The IR receiver on the TV receives these modulated signals and decodes them using the same protocol.
The IR TV remote control can be used to control various functions of the TV, such as turning it on or off, changing channels, adjusting the volume, and more.
