The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...
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 ...
This project measures the input voltage using an Arduino Uno and displays it on a 16x2 I2C LCD screen. It uses a simple voltage divider circuit to safely read voltages up to 12V. The Arduino reads an ...
