# Touch Sensor LED

Day 35 of the 100 Days 100 IoT Projects collection. Board: ESP8266.

Tap a capacitive touch pad to toggle an LED on the ESP8266 — no moving parts. Modern touch interfaces on a classic board.

## How it works

Your finger changes the capacitance of the touch pad, which the sensor chip detects and reports as a touch event. The ESP8266 toggles the LED on each clean touch, with debouncing so a lingering finger counts once. A button with no moving parts to wear out.

## What you'll learn

- Capacitive touch sensing
- Touch debouncing
- Solid-state inputs
- Modern UI on classic boards
