Transmitter And Receiver Circuit Diagram. Below pictures showing the rf transmitter circuit with breadboard setup. Components required for ir transmitter.
One is the transmitter circuit and the other is the receiver circuit the transmitter circuit will be connected to the 3 5mm audio jack for audio input and the receiver circuit will be connect to a speaker to play the songs. Ir transmitter circuit diagram. You can use any tsop but you need to generate ir of respective frequency as tsop.
The receiver circuit fig 2 is built around a single decade counter cd4017 ic4 and a few discrete components.
So we are using 555 timer in astable mode to oscillate the ir at 38khz frequency. The receiver circuit fig 2 is built around a single decade counter cd4017 ic4 and a few discrete components. Ic a0 a7 pins pin 1 8 are connected to the ground to set the address at 0b00000000. Below pictures showing the rf transmitter circuit with breadboard setup.
