With just a few extra products from the Adafruit store, you can make your very own Haunted Radio.
Vintage radios are irresistible. When you hear one spewing static, your natural response is to turn the dial and try to tune in a station. The anticipation! What will you hear? With this Haunted Radio project, you can decide for your guests or escape room attendees exactly what they'll hear, and you can even choose the frequency.
There isn't any pirate radio station involved here, either. Instead, the secret is a Feather 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.
