But what exactly is ESP32? Why is it so popular among hobbyists, engineers, and developers? In this beginner-friendly guide, we’ll explore what ESP32 is, what it’s used for, how it works, and everything in between.

By the end, you’ll have a solid understanding of the ESP32 ecosystem and why it’s such a game-changer for modern electronics projects. Imagine having a tiny computer, small enough to fit in your palm, yet powerful enough to control smart home devices, run sensors, and connect to Wi-Fi or Bluetooth. That’s exactly what the ESP32 offers. Whether you’re a hobbyist wanting to build your first IoT project or a professional designing advanced embedded systems, the ESP32 is versatile, affordable, and beginner-friendly. In simple terms, ESP32 is a microcontroller with built-in Wi-Fi and Bluetooth capabilities. This combination of features makes it a perfect choice for IoT applications, wearable tech, home automation, and more.

Let’s break it down. The question “what is ESP32?” often comes up among beginners. In technical terms, ESP32 is a low-cost, low-power system-on-chip (SoC) microcontroller developed by Espressif Systems. The ESP32 is a type of cheap, low-power microcontroller manufactured by Espressif Systems that is used in everything from homemade projects to academic, commercial, and industrial settings. If you’re looking for something to power your next DIY project, the ESP32 is a great choice. You can pick up an ESP32-C3 development board for less than $2.

This is one of the most popular ESP32 variants with a single-core 160MHz RISC-V processor, 400KB SRAM, 384KB ROM for code storage, 2.4GHz Wi-Fi, and Bluetooth 5.0. It has a range of interfaces, including I2C, SPI, two UART connectors, four ADC connectors, and an 11-pin GPIO interface. The price differs for different models, like the ESP32-C6 which includes built-in Thread and Zigbee functionality—perfect for use in a smart home. Many vendors will offer a bulk discount, which is perfect if you’re creating a fleet of devices for deployment around the home. By comparison, similar microcontrollers like the Raspberry Pi Pico W typically retail for much more. The ESP32’s secret weapon is its reliance on the RISC-V processor architecture, which is completely open source and requires no licensing in order to use.

The Seeed Studio XIAO ESP32-C3 is the perfect budget-friendly microcontroller for smart home projects. With Wi-Fi and Bluetooth built-in, it also features a super deep sleep mode for low power usage when it isn't doing anything. The compact size makes this ideal for building smart home projects, and ESPHome allows it to easily integrate into Home Assistant. In this article, I have discussed 10 ESP32 concepts that actually matter when building real projects. Each concept is explained with a practical example, showing not just what the ESP32 can do, but how to use those features correctly. If you already know the basics and want to build faster, smoother, and more reliable projects, this will take you there step by step.

The first thing you need to know is that the ESP32 isn’t just a regular microcontroller, it actually has two processing cores. That means it can literally do two things at once. For example, you could dedicate one core to handling Wi-Fi and the other core to reading sensor data, so your project runs much smoother. This is a huge advantage over boards like the Arduino Uno, which only has a single-core processor. Please note that by default the programs are run on core 1. Here’s a simple demo showing how to use the other core:
