Hundreds of projects from beginner to advanced — schematics, code, and videos.
Project that measures ambient light intensity with LDR sensor and displays it on Serial Monitor. Teaches the basics of analog sensor reading and serial communication.
LDR based night light project that automatically turns on the LED when the environment gets dark. Teaches automatic control logic with analog threshold comparison.
Security project that detects when the laser beam is interrupted via LDR and warns with buzzer and LED. Teaches the logic of light interruption detection with laser-LDR pair.
Advanced security system that activates the alarm when the laser beam is interrupted and can be reset by push button or IR control. Teaches multiple input source and state management.
Basic project that detects motion in the environment with PIR motion sensor and lights LEDs. Teaches digital sensor reading and motion detection logic.
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.
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.
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.
Project that measures the ambient temperature with NTC thermistor and displays it in Celsius on I2C LCD screen. It teaches how to calculate temperature from analog value with Steinhart-Hart equation.
