About LCD I2C 16x2. In the previous tutorial , we had learned how to use the normal LCD. However, wiring between Arduino and the normal LCD is complicated. Therefore, LCD I2C has been created to simplify the wiring. Actually, LCD I2C is composed of a norm

This chip converts the I2C data from an Arduino into the parallel data required by the LCD display. The board also comes with a small trimpot to make fine adjustments to the contrast of the display. In addition, there is a jumper on the board that supplie

The I2C LCD that we are using in this tutorial comes with a small add-on circuit mounted on the back of the module. This module features a PCF8574 chip (for I2C communication) and a potentiometer to adjust the LED backlight. The advantage of an I2C LCD is
