Projects using this component
Night Light with Ldr
LDR based night light project that automatically turns on the LED when the environment gets dark. Teaches automatic control logic with analog threshold comparison.
Laser Warning System
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.
Laser Security System
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.
Motion Detector with Motion Sensor
Basic project that detects motion in the environment with PIR motion sensor and lights LEDs. Teaches digital sensor reading and motion detection logic.
Doorbell and Light with Motion Sensor
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 with HC-SR04
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.
Lighting Led from Phone via Bluetooth
Wireless control project that turns LEDs on and off with commands sent from the phone with HC-06 Bluetooth module. Teaches Bluetooth data exchange over serial communication.
Reed Relay Door Sensor
Door open/close detection project with reed relay that lights green LED when the magnet approaches and red LED when it moves away. Teaches how to display status with magnetic sensor.
Bomb Animation with 4 7 Segment Display
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().
Flame Sensor Usage
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.
Gas Sensor Operation
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
Flame and Gas Sensor Alarm
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.
