Boards and platforms, real-world projects, sensors and peripherals, plus the coding and communication protocols that tie it all together — from first sketch to production-grade firmware.
5 focus areas inside Microcontrollers.
Board selection, pinouts, and platform comparisons — Uno, Nano, Mega, ESP32, Raspberry Pi Pico, and the trade-offs that pick the right brain for your project.
End-to-end builds — weather stations, robots, home automation — with BOMs, schematics, full code, and debugging walkthroughs.
Hall-effect, ultrasonic, DHT, servo, LCD, and OLED — wiring, libraries, and calibration for the parts that sense and actuate the world.
Arduino programming, Bluetooth, I²C, SPI, and Serial — the code patterns and bus protocols that make peripherals talk.
IDE setup, libraries, sketches, compile and upload troubleshooting, and the long-tail developer questions that fill out Arduino mastery.
