How to Use I2C LCD with Arduino | I2C Scanner Arduino | 16x2 LCD I2C Tutorial

In this tutorial, we dive into the world of Arduino and I2C LCD displays. We connect a 16x2 I2C LCD display to an Arduino Mega and guide you through the process of scanning the address and programming it.

This video is perfect for those who want to learn about:
1. **Connecting an I2C LCD display to an Arduino Mega**
2. **Scanning the I2C address**
3. **Programming an I2C LCD display**

We start by explaining the necessary components: a display, an Arduino Mega, and some wires. We recommend using male to female jumper wires for easy connection.

Next, we delve into the color codings of the I2C display spec, explaining the purpose of each pin: ground, VCC (voltage), SDA, and SCL. We then guide you through connecting these wires to the Arduino Mega.

Once everything is connected, we move on to programming. We explain how to use an I2C scanner to find the I2C address and provide a link to the code in the description below.

After finding the address, we show you how to install the necessary library for the LCD display I2C from the Manage Libraries in the Tools. We then guide you through testing out the code from the Examples section and modifying it to suit your needs.

By the end of this video, you'll have a fully functioning I2C LCD display showing a custom message.

i did the exact same and it cant find any device connected... i dont understand, since i already used a potentiometer on these 2 pins so the cause cant be defect pins. im trying to solve this issue for 2 days now
