Webb31 okt. 2024 · The hd44780 library will auto detect the I2C address and pin mapping. the code works perfectly fine on an arduino pro mini. the whole idea behind LiquidCrystal_I2C is to deal with low level "wire.h" calls. I assumed it should at least produce pulses on pin 2 and 3 of the arduino micro. WebbSo the better solution is to use an I2C LCD instead of typical 16×2 LCD. In this tutorial, we are using 16×2 I2C LCD, but LCD of any size will also work the same way as we will learn in this tutorial. The advantage of using an I2C LCD is that we only need to use four pins (including the VCC and GND pins) of Arduino to connect with this display. greigh lucas
