ESP32DIY is where I write down what I've built with the ESP32: from the first blinking LED to devices running 24/7 around the house. The goal is clear documentation with diagrams, working code, and honest notes about where people tend to get stuck.
What you'll find
- Projects: step-by-step guides with parts lists and source code.
- Experience: choosing boards, pin maps, saving power, debugging.
- Tools: Arduino IDE, PlatformIO, ESP-IDF, ESPHome, MQTT, Home Assistant.
Safety: only build projects that switch 220V mains if you understand electrical work. Always use isolated modules, an enclosure and a fuse, and disconnect power before wiring.
