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, ...

Reference circuit diagram of an Arduino-compatible LCD backpack is shown below. What follows next is information on how to use one of these inexpensive backpacks to interface with a microcontroller in ...

MFRC522 rfid(SS_PIN, RST_PIN); LiquidCrystal_I2C lcd(0x27, 16, 2); In the above code, I am creating the objects for the RC522 RFID and the I2C LCD module for proper initialization purposes. Storing ...

Put aside all of the projects that use an Arduino to blink a few LEDs or drive one servo motor. [IngGaro]’s latest project uses the full range of features available in this versatile microcon… ...

Before we get started into programming I2C using two Arduinos. We need to learn about the Wire library used in Arduino IDE.. The library <Wire.h> is included in the program to use the following ...

The I2C and SPI Education System is an Arduino shield that has been combined with a web based tutorial system to help users learn more about how to talk to I2C and SPI components.
