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 GitHub - nRF24/RF24Audio: Arduino library for streaming data/audio from analog inputs via NRF24L01 modules.
My references for this project:
a research paper PDF (PDF) A LOW-COST WIRELESS TV AUDIO TRANSCEIVER | mirugwe alex - Academia.edu
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
