Hundreds of projects from beginner to advanced — schematics, code, and videos.
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.
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.
Project that alarms with red LED and buzzer when flame is detected in the environment with the flame sensor module, and lights green LED in safe condition. Teaches digital flame detection logic.
Project that measures the gas density in the environment with MQ series gas sensor and alarms with LED and buzzer when it exceeds the threshold value. Teaches analog gas measurement and threshold comp
Advanced security project that uses flame sensor and gas sensor together and alarms with flashing LED and buzzer when fire or gas leakage is detected.
