Explore how to interface an led with Arduino Uno on pin 13 using a current-limiting resistor, then blink it with a setup and loop using delay.
Interface the serial monitor with Arduino to count LED on/off events in a blinking LED project. Set up 9600 baud and print counts with serial.print and serial.println.
Learn how to interface a push button to an Arduino using a pull-up resistor in an active-low configuration, with breadboard connections, pin nine as input, and serial monitor feedback.
Learn to build an active high push button circuit with a pull-down resistor on an Arduino, wiring the button to pin 9 and using digitalRead and serial output.
Explore how a push button wired as active low with a pull-up resistor controls an LED via Arduino pins 9 and 12, using digitalWrite and a current-limiting resistor.
Explore wiring an LED to an Arduino using a push button in active high with a pull-down resistor, and control the LED via pin 3 based on the button state.
This course takes complete beginners from their very first LED blink on Arduino to building small but powerful embedded projects. Using simple explanations and live coding, each lecture walks through the circuit connection, Arduino code, uploading, and testing so learners see every step of the process.
The journey starts with the classic LED blinking program and basic digital I/O so students become comfortable with the Arduino IDE, board connections, and uploading sketches. Next, the course introduces the serial monitor and counters, showing how to print data, debug code, and control LEDs interactively from the PC. As confidence grows, the lessons move into slightly larger mini‑projects such as pattern blinking, multi‑LED control, and simple sensor or button‑based tasks that combine inputs, outputs, and basic logic.
Throughout the course, the focus stays on practical hardware implementation: how to read circuit diagrams, place components on a breadboard, choose resistor values, and avoid common wiring mistakes that can stop a project from working. Every project is designed so students can build it at home with an Arduino board, a few LEDs, resistors, switches, and jumper wires, making the learning process highly hands‑on. By the end, learners will be able to understand existing Arduino example codes, modify them for their own ideas, and design simple embedded systems prototypes for academic projects or hobby applications.
If you want, the next step can be to expand this into advanced sections on sensors, motors, and communication protocols to create a full “Arduino from Zero to Hero” track.
