Hundreds of projects from beginner to advanced — schematics, code, and videos.
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.
Basic project that reads the digital value given by the reed relay sensor in the presence of a magnetic field in Serial Monitor. Teaches the principle of magnetic detection.
Door open/close detection project with reed relay that lights green LED when the magnet approaches and red LED when it moves away. Teaches how to display status with magnetic sensor.
Basic usage project that sequentially turns on and off the red, green and blue colors of the RGB LED. Teaches common cathode RGB LED control.
A project that creates a soft rainbow effect by gradually transitioning the colors of an RGB LED with analogWrite. Teaches the logic of color mixing and transition animation with PWM.
