Hundreds of projects from beginner to advanced — schematics, code, and videos.
Digital clock project showing time, date and day information read from DS1302 RTC module on I2C LCD screen. Teaches RTC and LCD integration.
Project that shows numbers from 0 to 9999 on a 4-segment 7-segment display with SevSeg library. It teaches multi-digit display logic with multiplexing (scanning) method.
Digital clock project showing hours and minutes with DS1302 RTC module and 4-segment 7-segment display. It combines real-time clock data and segment display.
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.
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.
Project that can turn 3 LEDs on and off independently with 3x4 keypad keys and perform batch control. Teaches multiple output control with keypad.
