Hi! :) I have been planning to do a project on transmitting audio through arduino using NRF24L01 RF Modules at the same time sending data commands. I am really a beginner in terms of audio circuits so I just want you, experienced people, to check if my Schematic diagram draft is correct. Thanks! :)
The project is based on the RF24 and RF24audio library for the arduino by TMRh20 https://github.com/nRF24/RF24Audio.
My references for this project:
a research paper PDF https://www.academia.edu/37370105/A_LOW-COST_WIRELESS_TV_AUDIO_TRANSCEIVER
and an arduino walkie talkie instructable https://www.instructables.com/id/Wristwatch-Walkie-Talkie/?fbclid=IwAR3ygIxQ04RkGxoig-NLiG63_Dy67fn-ugK_Q-e1ZIqhI5EkollqOw6UfOc
These are my Schematic diagram for the project:
The input circuit for the 3.5mm jack was based on the given circuit I found on the internet.
The receiver circuit for the was based on the given circuit I found on the project reference paper
