An educational resource for learning microcontroller programming with Arduino, STM32, ESP8266, ESP32, and Raspberry Pi Pico.

The Arduino Integrated Development Environment (IDE) is a powerful yet user-friendly platform designed for writing code and uploading it to various microcontroller boards. It supports a wide range of boards, including the Arduino Uno, STM32, ESP8266, ESP32, and Raspberry Pi Pico.

The Arduino IDE is available on Windows, Linux, and ARM Linux for the Raspberry Pi.

• Arduino Uno
  The ATmega328P-based Uno is ideal for beginners learning digital I/O, PWM, and serial communication.


• Arduino Due
  The ARM based Due is a powerful microcontroller board with a 32-bit ARM Cortex-M3 processor, offering high performance for complex projects.


• STM32
  STM32 ARM Cortex-M microcontrollers provide high speed and rich peripherals for complex embedded systems. Popular boards include the Bluepill.


• ESP8266
  A low-cost WiFi-enabled microcontroller suited for IoT projects, web interfaces, and connected devices.


• ESP32
  A dual-core microcontroller with WiFi + Bluetooth, offering higher performance for robotics, automation, and IoT.


• Raspberry Pi Pico / Pico W
  RP2040-based board with dual ARM Cortex-M0+ cores, ideal for both simple automation and advanced interfacing. The Pico W adds WiFi.

This platform focuses on practical applications of microcontrollers and assumes basic knowledge of the Arduino IDE and C/C++ programming.

• Overview of microcontrollers and embedded systems.
• Digital I/O, PWM, ADC, and basic programming concepts.
• Communication protocols: SPI, I2C, UART.
• Interrupts, timers, and real-time control.
• IoT networking with ESP8266 and ESP32.
• Low-power and interfacing projects with Raspberry Pi Pico.

• Home automation systems using ESP8266/ESP32.
• Temperature & humidity monitoring with Arduino and Bosch BMP/BME sensors.
• Real-time clock and data logging with STM32 boards.
• Simple WiFi web app control using ESP modules.
• Motor and servo control using Raspberry Pi Pico.
