First Arduino project..wireless microphone system with NRF24L01

Sensors Sound & Audio

Hello there,

Was wondering how I can attach a handheld hi-z microphone into a arduino-powered nrf24 (designated as a transmitter) and have another arduino as the reciever will be connected to an amplifier. Therefore in theory this will give me wireless communication.

I’ve only found codes that deal with powering motors wirelessly but nothing that can transmit the small voltages that a microphone might produce.

Any help would be much appreciated.

Doing a search on “nrf24 wireless mic” brings up a number of hits.

https://tmrh20.github.io/RF24Audio/ is a library that handles audio over the NRF

https://cassiopeia.hk/walkietalkie/ is an example of using the above library

I am not sure how much latency (delay) this solution has and whether it will cause problems with your application.
