Abstract: This research explores the development of an Arduino-based Fingerprint Scan for Attendance-taking System aimed at addressing the shortcomings of traditional attendance methods in educational ...

Unique clocks are a mainstay around here, and while plenty are “human readable” without any instruction, there are a few that take a bit of practice before someone can glean the current time from them ...

DS3231 is a RTC (Real Time Clock) module. It is used to maintain the date and time for most of the Electronics projects. This module has its own coin cell power supply using which it maintains the ...

An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

Abstract: This study describes the optimization of solar cell electrical power with variations in slope angles using timer-based panel drive (DS3231 RTC) and light sensor (LDR). There are three solar ...
