This Arduino sketch demonstrates how to use an I2C-enabled LCD display with an Arduino board. The LiquidCrystal_I2C library is used to control the LCD, and the sketch also includes a function to ...

Library Support: Utilizes existing Arduino libraries for I2C communication and LCD control, ensuring compatibility and ease of use. Example Projects: Explore a collection of example projects ...

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 ...

The first thing to do in the program is to include all the required libraries. Here in my case, I have included “LiquidCrystal_I2C.h” library for using the I2C interface of an LCD and “Wire.h” for ...

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 ...

In this tutorial we will see how to interface NodeMCU with 16x2 LCD without using I2C communication. Here we will interface 16x2 LCD using shift register SN74HC595. ... Program is simple and easily ...

It can switch relay, a light bulb, or some analog signal, just like with a electromechanical relay. I will add example code for python/micropython later that shows how to control the I2C bus and the ...
