John Park's Coffee Detonator @adafruit @johnedgarpark #adafruit
133Use a high-voltage AC power source to trigger a Feather microcontroller-driven coffee grinder. This guide will show you how a magneto, generator, or other AC power source can be safely converted into a small DC signal easily read by an Arduino-compatible microcontroller. Then, the microcontroller can trigger a 120V relay to turn on any AC device or appliance, such as a coffee grinder, blender, lamp, or pump.
