Course Overview7:02
In this lecture, you’ll get an overview of the course structure, the learning goals, and what tools or hardware you’ll need. We’ll also briefly discuss what to expect in terms of hands-on practice and real-world applications. This is your roadmap for mastering ATmega328P-based embedded development.
Microcontrollers and Types22:34
We begin by exploring what microcontrollers are, basic structure of microcontroller and their role in embedded systems. You’ll learn about Harvard vs. Von Neumann architecture, the classification of microcontrollers, and the types commonly used in industry today.
Introduction to ATmega328P18:36
This lecture dives into the specifications, pinout, and architecture of the ATmega328P. You’ll learn why it’s such a popular choice in embedded systems and get familiar with its internal blocks such as timers, ADC, UART, and I/O ports.
Overview of Arduino and why NANO is used10:02
In this you'll came to know, why the Arduino Nano is used in this course—highlighting its small size, USB programming capability, and compatibility with the ATmega328P. You’ll learn how it simplifies development while still allowing low-level access to microcontroller features.
Getting Started with Arduino Nano: Installation, Setup, and First Program3:51
In this hands-on session, we walk you through installing the Arduino IDE, setting up your Arduino Nano, and writing your first embedded program—a classic LED blink. In this implementation, Arduino code is used in place of standard C language for board-level programming.

Note: Please install the appropriate version of the Arduino IDE according to your operating system (Windows, macOS, or Linux).

GPIO Basics6:30
In this lecture, you’ll understand how General Purpose Input/Output (GPIO) pins work. We explain how to configure pins as input or output, use internal pull-up resistors, and safely interface with external components.
Programming LED Blink on ATmega328P5:20
You’ll write a simple LED blink program using pure C language instead of Arduino Programming Language. The goal here is to introduce basic digital output control using a timing loop.

Note: Refer to the official ATmega328P datasheet for register-level programming and configuration details while coding.
Digital I/O (LEDs, push buttons)5:12
Explore how to read the state of a push button and control output devices based on input logic. You’ll also understand hardware debounce, and common input-related issues.

Note: Refer to the official ATmega328P datasheet for register-level programming and configuration details while coding.

Digital I/O (LEDs and Push Buttons)

Interfacing an LDR with the ATmega328P using ADC9:46
You’ll learn how to read analog values using the built-in Analog-to-Digital Converter (ADC) of ATmega328P. We interface an LDR (Light Dependent Resistor) to turn off/on LED and convert analog voltage to digital values.

Note: Refer to the official ATmega328P datasheet for register-level programming and configuration details while coding.
Interrupt12:55
In this lecture, we introduce hardware interrupts and how they’re used to respond immediately to events (like button presses). You’ll configure an interrupt pin and write an Interrupt Service Routine (ISR) in embedded C.

Note: Refer to the official ATmega328P datasheet for register-level programming and configuration details while coding.
TIMER / COUNTER26:57
Timers are key to real-time embedded systems. We cover the difference between timers and counters, their registers, and how to use Timer0 or Timer1 to trigger tasks at precise intervals—like blinking without using "delay()".

Note: Refer to the official ATmega328P datasheet for register-level programming and configuration details while coding.

UART (Communicating with other microcontrollers)20:27
Learn to use the Universal Asynchronous Receiver Transmitter (UART) for serial communication. We explain baud rate settings, data framing, and how to transmit/receive data using the Serial Monitor.

Note: Refer to the official ATmega328P datasheet for register-level programming and configuration details while coding.
I2C12:27
We introduce the I2C (Inter-Integrated Circuit) protocol, used for communication with external sensors and devices. You’ll learn how to configure I2C master/slave roles, read/write data, and troubleshoot address conflicts.
