Hundreds of projects from beginner to advanced — schematics, code, and videos.
IR control project that can independently turn on/off 3 LEDs with different keys of the remote control. Teaches how to match remote control codes and control multiple outputs.
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.
A project that lights the LED and plays the doorbell melody with a buzzer when the PIR sensor detects motion. Combines motion detection with sound and light notification.
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.
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.
Project showing numbers from 0 to 9 in sequence on a 7 segment display. It teaches the logic of creating numbers by controlling the segment pins.
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.
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
