Microcontrollers
Small computers on a single chip that control electronic devices
Introduction to Microcontrollers
A brief explanation of what microcontrollers are and their role in electronics.
Microcontrollers are small computers on a single chip that control electronic devices by reading inputs from sensors, processing the data, and controlling outputs such as motors, LEDs, relays, and displays.
Common Types of Microcontrollers
Arduino Uno
Arduino Uno is one of the most popular beginner-friendly microcontrollers. It is widely used with sensors such as DHT11, HC-SR04, PIR, Gas Sensors, LDR, and ACS712 due to its simplicity, large community, and extensive library support.
ESP8266
ESP8266 is a WiFi-enabled microcontroller mainly used for IoT projects. It connects sensors to the internet for real-time monitoring of temperature, gas levels, water level, and motion detection.
ESP32
ESP32 is an advanced dual-core microcontroller with built-in WiFi and Bluetooth. It supports almost all the sensors listed above and is widely used in smart automation, robotics, and wireless sensor networks.
Raspberry Pi Pico
Raspberry Pi Pico is a powerful and low-cost microcontroller based on the RP2040 chip. It is used for high-speed sensor data acquisition, robotics control, and educational embedded systems.
STM32
The STM32(F103C6T6) Development Board is a high-performance ARM-based microcontroller used for fast sensor data processing and real-time embedded control applications.
ATmega328P Standalone
ATmega328P is the core chip used in Arduino Uno. It can be used independently for compact embedded projects involving motion sensing, sound detection, current measurement, and obstacle detection.
