DISPLAY MODULE I2C
Display Module I2C_LCD is an easy-to-use display module, It can make display easier. Using it can reduce the difficulty of make, so that makers can focus on the core of the work. We developed the Arduino library for I2C_LCD, user just need a few lines of the code can achieve complex graphics and text display features.
The solution is to use an I2C LCD Display. It consumes only two I/O pins that are not even part of a set of digital I/O pins and can also be shared with other I2C devices.
