This project demonstrates how to connect and display text on a 1602 LCD screen using an I2C backpack. A 4-channel bidirectional logic level shifter is used to safely translate the 3.3V I2C signals of the ESP32 to the 5V signals required by the LCD module. After uploading, the LCD shows a welcome message and updates an uptime counter every second.
