Description

In this workshop, you’ll build a smart lighting project using an ESP32 and an RGB LED. A single button press will cycle through predefined colour modes, with smooth transitions powered by Pulse Width Modulation. The result is a responsive, interactive light that showcases how simple components can create dynamic, real-world effects.

This project blends digital input with analogue-style control, offering a hands-on introduction to microcontroller programming and interactive design. It’s a compact, creative build that lays the foundation for more advanced future smart lighting workshops. 

What You’ll Learn

A Working Smart Light
It responds to your input using real hardware and logic you control.
Confidence with ESP32 I/O
Wire components and write logic that controls real-world outcomes.
Skills for More IoT Projects
Lay the groundwork to build more advanced smart devices with confidence.

It's Nice To Meet You — Welcome to Vman Builds!

Vijay Madas

Hello, I'm Vijay. I'm a practical engineer and a lifelong maker. I created Vman Builds to help people learn real engineering skills by building real projects.

Over the years as an educator, I've helped countless learners go from “not sure where to start” to confidently creating projects they’re proud of. You don’t need an engineering degree—just curiosity and a willingness to learn.

My workshops are designed to guide you step-by-step, with simple goals in mind:

  • Help you build something that actually works.

  • Teach you how and why it works.

  • Give you the confidence to want to keep learning and building more.

Whether you're here to level up your skills or simply looking to explore your curiosity, you're in the right place.

Let's create something great together.
