This repository contains Arduino code and documentation for interfacing with an I2C (Inter-Integrated Circuit) LCD (Liquid Crystal Display). The code is designed to facilitate easy integration of I2C ...

Arduino library for the I2C LCD display, typical 20x4 characters. The library is inspired by the excellent New-LiquidCrystal library by F. Malpartida. Therefore the interface is kept quite identical, ...

Learn to build an RFID based attendance system using Arduino with step-by-step instructions, circuit diagrams, and complete code. This $35 DIY project replaces expensive commercial systems with ...

To communicate with each LCD via I2C, two TCA9548A I2C multiplexers are connected to an Arduino, along with an RTC to keep track of the time and date itself.

Next steps shows how the master (Arduino) reads from the slave I2C device. Wire.requestFrom(address, 1) command expects to receive 1 byte of data from the TC74 sensor. Wire.available() waits for data ...

[Wayne] wrote in to share an item he just finished working on, an I2C GPS shield for the Arduino. While other GPS solutions have existed for quite some time, his caught our eye due to its feature l… ...
