Optical Fingerprint Sensor with Arduino

Overview Fingerprint Sensor is an alternative device for security and verification purposes. In modern technology, it is included in high-end smartphones as an alternative unlock against pass codes or pattern swipes. One application of the fingerprint sensor is that of an attendance monitoring system, which is widely used in offices. We are going to create a system which will greet

Motion Detector using PIR Module

Overview A passive infrared (PIR) sensor is a type of sensor that detects movement using infrared radiation. Typically, a PIR sensor is used for home automation, motion detection, and many more. In this project, the PIR sensor is used for motion detection, and a light-emitting diode is used as an

Running Message using 8×8 LED Matrix MAX7219 driver

Overview Visual cues ,e.g. hand signals,  are a time-tested communication schemes that help humanity survive throughout the history. It provides a simple, quick, yet understandable common ground for communication. Light-emitting Diodes (LEDs) are  typical electronic elements to demonstrate a visual cue, such as indicating a device's ON or OFF states.
