Welcome to JustElectronicX!
JustElectronicX is a free hub of beginner-friendly electronics and IoT tutorials. Whether you're blinking your first LED or building a WiFi-connected sensor network, you'll find step-by-step guides for Arduino, ESP32, ESP8266, and Raspberry Pi Pico — plus the fundamentals of basic electronics.
What you'll find here
- Get Started guides — hardware setup, IDE/software installation, and your first program for every supported board.
- Project tutorials — wiring diagrams, code, and explanations for real projects, from simple blinks to sensor-based builds.
- Built-in examples — walkthroughs of common board examples so you understand exactly what's happening.
- Basic electronics — components, circuits, and concepts that apply across every platform.
Why JustElectronicX?
No setup required to flash. JustFlash lets you flash pre-built firmware to your Arduino or ESP board directly from your browser using WebUSB — no IDE installation needed.
Mistakes are part of learning. Every guide is written so you can follow along at your own pace, double-check your wiring, and try again if something doesn't work the first time.
Clear, focused guides. Each tutorial covers wiring, code, and explanation — so you understand why it works, not just how to copy and paste.
Community-driven. Have feedback, found an issue, or want to suggest a tutorial? Reach out through the Contact page.
