🔥 PlatformIO, combined with Visual Studio Code (VS Code), is one of the most powerful and professional ways to program microcontrollers such as ESP32, ESP8266, Arduino, STM32, RP2040, and many others. This step-by-step guide is written for beginners, but it also includes best practices used by professionals. By the end, you’ll be able to create,

Ever wanted to keep an eye on your home’s temperature and humidity while you’re away? So, let’s build a custom, affordable IoT monitoring device using an ESP32 microcontroller and a DHT sensor that sends temperature and humidity 🌡️ data to ThingSpeak (a popular IoT analytics platform). You’ll be able to view real-time graphs and receive

Today, we’ll create a web server on the ESP32 that displays a control interface with two buttons. When you click these buttons from a browser, the ESP32 will toggle the corresponding outputs, controlling LEDs or replace them with relays to control high‑voltage devices like lights, fans, or sockets ⚡ 🧠 Before We Begin: If you’re completely

Want to monitor temperature and humidity using your ESP32? Today, we’re going to transform our ESP32 microcontroller into a real-time temperature and humidity monitoring station that serves data through a web interface.  Before We Begin: If you’re completely new to the ESP32, I recommend checking out my previous blog post, an Ultimate ESP32 Beginner’s Guide. We’ve

The ESP32 is one of the most popular microcontrollers in the maker, IoT, and DIY electronics world. Whether you want to build smart home projects, wireless sensors, or connected robots, the ESP32 is often the first (and best) choice. 1️⃣ What Is the ESP32? It is a low-cost, low-power microcontroller with built-in Wi‑Fi and Bluetooth,
