From the project

Smart esp32-powered desk lamp

This is a home assistant controlled CWWW desk lamp with capacitive touch buttons, made with ESPHome and ESP32-C3.

I made this project as I wanted to learn more about capacitive touch sensors and how to use them with ESPHome. I also wanted to make a simple desk lamp that could be controlled with Home Assistant.

- Capacitive touch buttons to control the brightness and color temperature of the LEDs. - Home Assistant integration.
