Microcontroller Tutorials with Code from Scratch
Controllerstech.com is dedicated to teaching STM32, ESP32, and embedded systems through practical, hands-on tutorials. All examples are built from scratch using datasheets and reference manuals, and every project is tested on real hardware to ensure accuracy and reliability. The goal is to help you gain complete control, deep understanding, and the confidence to build real-world embedded applications.
