Touch-Based Doorbell using Arduino and Touch Sensor

The Touch-Based Doorbell is a smart and hygienic alternative to traditional mechanical doorbells. Built using an Arduino Uno and a TTP223 capacitive touch sensor, this project allows users to ring the doorbell simply by touching a sensor pad—no pressing required. It’s a great solution for smart homes and public spaces where minimizing physical contact is important.

When a user touches the sensor, it sends a signal to the Arduino, which then activates a buzzer to produce a chime sound. The system is simple, cost-effective, and easy to build. It can also be expanded by integrating features like wireless alerts or camera systems.

Earthquake Detector using Arduino and Vibration Sensor

The Earthquake Detector is a basic yet effective project built using an Arduino Uno and a vibration sensor (SW-420) to detect tremors or seismic activity. The sensor continuously monitors ground vibrations. When sudden or strong vibrations are detected, it sends a signal to the Arduino, which then triggers an alarm using a buzzer or LED to alert nearby individuals.

This system is simple to build and helps demonstrate how vibration sensing can be used in early warning systems. It can be further enhanced by integrating a 16×2 LCD to display real-time status or even a GSM module to send alerts remotely.

Traffic Light Controller using Arduino and Traffic Light Module

The Traffic Light Controller project uses an Arduino Uno and a traffic light module (or individual red, yellow, and green LEDs) to simulate a real-world traffic signal system. It’s an ideal beginner project for understanding automation, timing, and microcontroller-based control systems.

The Arduino is programmed to control the lights in a specific sequence—green (go), yellow (wait), and red (stop)—each with a set time duration. This cycle runs continuously, mimicking an intersection traffic light system. Optional enhancements like pedestrian buttons, vehicle sensors, or countdown timers can be added to make the project more interactive and realistic.

RFID-Based Attendance System using Arduino

The RFID-Based Attendance System is a smart and contactless method to record attendance using RFID technology. It uses an Arduino Uno, RC522 RFID reader, and RFID tags/cards assigned to individuals.

When a person taps their RFID card near the reader, the system reads the card’s UID and checks it against pre-stored data in the Arduino. If the UID is valid, a 16×2 LCD (with I2C) displays a message like “Attendance Marked”, and a buzzer or LED can signal a successful scan. Invalid cards show an “Access Denied” message.

Flame Detector Alarm using Arduino and Flame Sensor

The Flame Detector Alarm project is a safety-focused system that uses an Arduino Uno and an IR flame sensor to detect fire or flame and trigger an alert. It is ideal for early fire detection in homes, labs, or industrial areas.

The IR flame sensor detects infrared light emitted by fire within a specific range. When a flame is detected, the sensor sends a signal to the Arduino, which immediately activates a buzzer and an LED indicator. This provides both audible and visual warnings of potential fire hazards.
