This tutorial demonstrates how to use our FC-113 IIC/I2C Serial Interface Adapter Module For 1602 LCD Display.  These serial interface modules simplifies connecting an Arduino to a 1602 Liquid Crystal display using only 4 wires.  This module uses the PCF8574T IC chip.

TIP for those WHO bought <===> https://www.amazon.de/dp/B079T1BW6T/  on #Amazon <==> from #AZDelivery: The #I2CAddress which I got delivered was "0x3F" and NOT "0x27, 0x38"!!; Check the I2C Address with this #Sketch <===> https://playground.arduino.cc/Main/I2cScanner  <===> SDA <==> PIN 4 / SCL <==> PIN 5 on Arduino

This very simple sketch scans the I2C-bus for devices. If a device is found, it is reported to the Arduino serial monitor.

This sketch is the first step to get the I2C communication working.

The sketch shows the 7-bit addresses of the found devices as hexadecimal values. That value can be used for the "Wire.begin" function which uses the 7-bit address. Some datasheets use the 8-bit address and some example sketches use decimal addresses.
