Hundreds of projects from beginner to advanced — schematics, code, and videos.
A project that lights the LED and plays the doorbell melody with a buzzer when the PIR sensor detects motion. Combines motion detection with sound and light notification.
Simple piano project with 8 buttons and buzzer to play notes from C to high C. Teaches how to simulate a musical instrument by assigning different frequencies to each button.
Project that measures distance with HC-SR04 ultrasonic sensor and displays the result in cm on Serial Monitor. It teaches the principle of distance calculation with sound wave.
Parking sensor project with HC-SR04 sensor that increases the buzzer beep rate as the object approaches and warns with LED. Teaches feedback logic proportional to distance.
Project that prints character by character on a 2x16 LCD screen and displays a looping message by clearing the screen. The LCD library teaches how to use the setCursor and print functions.
A project that creates an animation effect of the text moving left and right on the LCD screen and hitting the walls. Teaches dynamic setCursor positioning and text animation logic.
A project that displays the readings from the HC-SR04 distance sensor in cm in real time on a 2x16 LCD screen. It combines sensor data and LCD display.
The project that prints messages by controlling the LCD screen with only 2 cables (SDA, SCL) thanks to the I2C module. Teaches how to save pins with I2C protocol.
Project that performs height measurement by calibrating with HC-SR04 sensor and I2C LCD screen. It offers a practical application by managing calibration and measurement steps with two buttons.
Wireless control project that turns LEDs on and off with commands sent from the phone with HC-06 Bluetooth module. Teaches Bluetooth data exchange over serial communication.
Basic usage project that positions the servo motor to 0°, 90° and 180° angles in sequence. Teaches servo library and angle control logic.
Project that controls the servo motor in real time by converting the potentiometer value to the range 0-180°. teaches map() function and analog-servo integration.
