Hundreds of projects from beginner to advanced — schematics, code, and videos.
Bomb animation project that counts down on 4 7 segment display, can be accelerated with potentiometer and canceled with buttons. Teaches the use of timer, multiple input control and millis().
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.
Project that reads the serial number in Serial Monitor when the card or keychain is approached with RC522 RFID module. Teaches the basics of SPI communication and RFID reading.
Authentication project that gives access permission with green or red LED by comparing the card ID read with the RC522 RFID module with the registered ID.
Project that measures the ambient temperature and humidity value with the DHT11 sensor and displays it on the I2C LCD screen. Teaches the use of digital temperature/humidity sensor.
Digital voltmeter project that measures voltage in the range of 0-55V with voltage divider circuit and displays the result on I2C LCD screen. Teaches voltage divider formula and analog measurement cal
A project for one-way data transfer between two Arduinos via serial communication. It detects the button press on the transmitter side and teaches to control the LED on the receiver side.
A project that transfers data bidirectionally between two Arduinos via serial communication. Both boards both read buttons and send data and receive data and control LEDs.
Control project that lights LEDs in 4 different directions according to the X and Y axis values of the joystick module. Teaches analog joystick reading and direction detection logic.
Pan-tilt project that independently controls two servo motors in X and Y axes with joystick module. Teaches the logic of joystick-servo integration and position tracking.
