John Park’s Mystery Box: The Haunted Radio demo @adafruit @johnedgarpark #adafruit

Breathe spooky life into an old radio by adding a Feather microcontroller to read the dial and play mysterious sounds and music!
The secret is the microcontroller reading the dial position with a magnet sensor, and an attached Music Maker FeatherWing with amplifier to play back your pre-recorded message over the radio’s speaker.
