I am attempting to build an audio recorder with what supplies I have on hand. I intend to use the max4466 as the input and one of several microcontroller boards in the process. I have at my disposal an Elegoo Uno R3, Arduino Nano 33 BLE, Arduino Nano CH340, and an ESP-32S board. I would like to use one of the Nano boards. I would also like to use a pushbutton (I have one) to begin and end the recording.
I've successfully run this project from Adafruit website to measure input but am having difficulty a) recording longer and b) converting to audio file such as .wav or .mp3. I am running macOS big sur and have had no issues with Arduino IDE or board connection.
My skill level is approx 4/10.
Any tips? Thanks a ton!
