I needed a radio receiver that would just turn on when I applied power and remember what station/volume it was at... Surprisingly few affordable retail options.
- ESP8266 - This was built around a WEMO D1 Mini
- RDA5807 - The actual FM receiever, I will one day provide schematics for both starting from scratch, and starting from those tiny modules.
- /set?args - Where ars can be any combination of the following seperated by &:
- volume=10 - sets the volume to 10
- frequency=8980 - sets the frequency to 89.8
- bass=1 - enables bass boost
- hostname=radio - sets a new host/mdns name
- /save - store current values persistently
- /reset - performs a soft reset on the tuner
