Webhook Gong Trigger
This project turns an ESP32 microcontroller into a web-connected gong trigger that rings a solenoid-driven gong when a webhook is received. Perfect for notifications, alerts, or creative IoT integrations, the device listens for HTTP requests and activates the solenoid to strike the gong with a satisfying sound.
The guide includes a complete wiring diagram showing how to connect the solenoid and power circuitry to the ESP32, a full parts list, Arduino firmware with WiFi and webhook handling, and step-by-step assembly instructions. Builders will learn how to set up WiFi connectivity, handle HTTP requests, and control high-current devices safely from a microcontroller.
