Test I2C LCD Address Change

A basic I2C address change test using an I2C LCD module. The module’s address was changed by soldering different combinations of the A0, A1, and A2 address jumpers. Each setting was checked using an I2C scanner, covering all eight addresses from 0x27 to 0x20. A reference table for modules with a default address of 0x3F is included at the end. Conducted as a basic I2C communication test in a FabLab environment. This project is also archived on the blog: https://polnalab.com/arduino/intermed...
