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.
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.
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.
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 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
