Project 1 - Interfacing a 16*2 LCD with Arduino using I2C protocol

AIM

In this project implementing the Code for “Interfacing a 16*2 LCD with two Arduino’s (one for Master and one for Slave) using Inter-Integrated Circuit (I2C) communication protocol” by sending the message to LCD using I2C communication protocol and display the message on LCD screen.

Key Highlights of the Project:

• Using the inter-integrated circuit communication protocol, transferring the data i.e. the message we want to display is sent to the LCD.
• Two Arduino’s connected to the LCD display and the communication is executed using I2C protocol between Arduino and the LDC display.
• Communication between Arduino and 16*2 LCD using I2C protocol.
• Displaying the message sent by Master and received by slave i.e. LCD display.

project summary:

The code is for a project that uses two Arduino boards to communicate with each other using the I2C protocol. The first board, labeled as the "Master," sends data to the second board, labeled as the "Slave." The Master board reads data from a potentiometer and maps it to a value between 0 and 127 before sending it to the Slave. The Slave board receives the data and displays it on an LCD screen. The Slave also sends data back to the Master, which is read from a potentiometer and mapped to a value between 0 and 127 before being sent. The Master receives the data and displays it on an LCD screen. The code also uses the Serial library to print the received data on the serial monitor.
