Long Range Wireless Audio Transmitter And Receiver Circuit Diagram. This generally comprises a transmitter and a receiver pair. We have published lots of radio transmitter circuits which will help you learn a lot about basic communication electronics.
Here we have used multiple ir leds to increase the distance. Also learn here about how ir sensor works. Apply power to both transmitter and receiver sections using two 9v batteries.
This is a simple ir audio link circuit which is used to transmit audio signals wirelessly.
Connect an 8 ω speaker at the output of lm386 audio amplifier ic. Make sure that distance between transmitter and receiver sections is below 30 cm. Initially give transmitter and receiver the connections separately as per the circuit diagram. Rf transmitter and receiver.
