I’m going to build a FM radio using an ESP-32 + the FM radio module to listen to music, news etc. I will be able to change the frequency via a rotary encoder and use a display built in to the ESP-32 board to see what frequency I am on
I’m going to need to setup the FM radio module for the ESP-32 which will include a receiver, an amplifier and a speaker for audio. Then I will connect an OLED display to the ESP-32 to display the frequency on the radio (eg 98.1). I will also need to use a rotary encoder to be able to change the frequency.
