Build a self-contained Dial-a-Song using a Western Electric 2500DM telephone and a Feather RP2040 + mono amplifier. You can have people dial a number to hear a song or message played through the handset earpiece.
The CircuitPython keypad library makes it simple to read the Touch Tone keypad matrix.
