Touch Activated Control Kit

Overview

This DIY project builds a touch-controlled switch. Touching a TTP223 sensor pad makes an Arduino Nano toggle a relay that can switch a lamp or other device on and off.

How It Works

1. The TTP223 touch sensor outputs a signal when your finger touches the pad.
2. The Arduino Nano reads the signal and toggles its state.
3. The relay module switches the connected load on or off accordingly.

Applications

• Touch-controlled lamps - a modern, button-free switch
• Home automation - a base for smart switches
• Relay learning - safely control higher-power devices from a microcontroller

FAQ

Do I need coding experience? No prior experience is required - this kit is built around one specific project, and the full code is freely available. See the build guide above.

What tools do I need beyond what's included? A computer with the free Arduino IDE (or ESP8266 board support, where applicable) installed to upload the code. No soldering is required for this build.

Can I reuse the parts afterward? Yes - every component in this kit is a standard, reusable part you can use in future projects, not a single-use kit.
