INTRODUCTION TO MICROCONTROLLERS
WHAT IS A MICROCONTROLLER?
A microcontroller is a small computer on a single chip that can be programmed to perform
specific tasks. It includes:
CPU (Processes instructions)
Memory (Stores data and programs)
Input/Output Pins (To connect sensors and other devices)
Reset USB Interface LED Pin Header for
Switch Chip 13 digital I/O
USB Part Clock
Oscillator

Microcontrollers are used in robotics, automation, and smart devices, making them essential
for projects in this book!
OVERVIEW OF ARDUINO
The Arduino is a popular open-source microcontroller board used by hobbyists, students, and
engineers.
Key Components of an Arduino Board:
Microcontroller (ATmega328P) – The brain of the board.
Digital and Analog Pins – Used to connect components like LEDs, sensors, and motors.
USB Port – For uploading code from a computer.
Power Jack – To connect an external power source.
Reset Button – Restarts the program.
Fun Fact: The Arduino was designed for beginners, making it one of the easiest microcontrollers
to learn!
