Most of the LCD library commands are located at : Arduino LCD Reference. The code can be modified to connect the LCD to any of the PORTs by changing the "#define". Arduino Tutorial: HX711 Load Cell Amplifier (Weight Sensor Module) + LCM1602 IIC V1 LCD Leave a reply In this tutorial, it is shown how to utilize an Arduino Uno, a HX711 breakout board, and a load cell in order to measure weight. The row of pins is attached to the same row of pins on any HD44870-compatible LCD. Para utilizar este módulo é preciso baixar a biblioteca do mesmo, disponível neste link. For this tutorial,it is necessary to download and install the "LiquidCrystal_I2C" library. This library is for character LCDs based on the HD44780 controller connected via I2C bus using the cheap I2C backpack modules based on the PCF8574(T/A). h library, for having access to all the functionality needed to send commands to the display.
