Random Nerd Tutorials
Hands-on microcontroller and IoT tutorials for common maker boards.
Random Nerd Tutorials publishes practical electronics guides for ESP32, ESP8266, Arduino, Raspberry Pi, Raspberry Pi Pico, MicroPython, and home-automation projects. The site combines free project tutorials with downloadable resources and paid courses/eBooks for more structured learning paths.
Why it stands out
- Strong focus on popular low-cost IoT boards rather than general electronics theory.
- Covers both microcontroller code and connected-project infrastructure such as MQTT, Firebase, Node-RED, and web dashboards.
- Large archive is split by hardware family, making it easier to find projects for a specific board.
- Includes applied project patterns like ESP-NOW, BLE, web servers, camera capture, and sensor visualization.
Good to know
- Some deeper learning materials are sold as paid courses or eBooks rather than fully free articles.
- Tutorials are tightly centered on specific boards and ecosystems, so they may not translate directly to other microcontrollers.
- Hardware, library versions, and IDE choices matter; users may need to adapt examples if their board or software setup differs.
Under the radar: Before starting a guide, check whether it targets Arduino IDE, ESP-IDF, or MicroPython—the same board family appears across different programming stacks, and the setup steps are not interchangeable.
Photos
ESP32 and ESP8266 makers who need board-specific wiring, code, and IoT project walkthroughs. Build web servers, BLE projects, camera modules, clocks, and sensor dashboards. Learn MicroPython or Arduino IDE workflows through finished hardware examples. Set up Raspberry Pi-based home automation using tools like MQTT, Node-RED, and databases. Compare project ideas before buying modules, sensors, or development boards.
Project libraries organized by board and topic; step-by-step electronics tutorials with code-focused examples; sections for ESP32-CAM, Raspberry Pi, Pico, Arduino, and MicroPython; free eBooks/resources; paid courses and eBooks covering ESP32, web servers, home automation, Firebase, and beginner electronics.
