DESCRIPTION : This project demonstrates how to interface a 4x4 matrix keypad with an LCD (16x2) display using an Arduino board. The system captures key presses from the user via the keypad and ...

This repository contains a complete and well-documented digital clock built using an Arduino Uno or Arduino Nano, a DS3231 high-accuracy real-time clock (RTC) module, and a 16×2 I2C LCD display. The ...

One of the limitations of the small 8 bit microcontrollers like the Atmel ATMega family adopted by the Arduino board, is the reduced number of I/O ports. Among the main advantages of these ...

The pH meter project features open software and open hardware design circuit which can be connected with an electrode pH sensor made of glass. The device is termed as pHduino which can operate by ...

Real-time environmental monitoring is increasingly important in agriculture, industrial automation, smart homes, and healthcare. The real-time data monitoring system measures and displays ambient ...
