No More Buttons! Add Touch Control to Your ESP32

Описание: Stop using clunky buttons! In this video, we’re diving into the world of capacitive touch for the ESP32. Whether you’re building a sleek bedside alarm clock or a smart home controller, touch sensors offer a modern, durable way to interact with your projects.

I'll cover two distinct methods to help you decide which is best for your build:

A. Built-in Touch Pins: How to utilize the ESP32’s native capacitive GPIOs (no extra hardware required!).
B. TTP223 Sensor: How to integrate this popular, inexpensive module for dedicated touch switching.

What’s inside:
• Getting Started: A beginner-friendly breakdown of how capacitive touch works.
• Hardware Setup: Wiring diagrams for both the internal pins and the TTP223.
• Arduino IDE: C++ code examples (perfect for your bedside clock alarms).
• ESPHome: How to quickly add touch sensors to Home Assistant with just a few lines of YAML.

Whether you're a total beginner or just looking to move away from mechanical switches, this guide has everything you need to get "in touch" with your ESP32.
