Hub erlaubt Anschluss mehrerer I²C-Geräte mit gleicher Adresse am selben Bus
I²C-Displays und Sensoren haben oft nur eine Adresse, was die Verwendung mehrerer gleicher Teile an einem Bus ausschließt. Mit diesem Hub geht es doch.

Well, I made some searches on the internet and I found the right answer on a forum about this error, which says that one should scan the I2C Address of the device and replace the “lcd.init();” by “lcd.begin (0x3F,16,2);” whereby “0x3F” is the I2C Address of my LCD1602/I2C module. I scanned to find out the I2C Addess with this sketch, please check here:

Displaying Temperature/Humidity on a I2C LCD  We were already playing around, as seen on my tutorials below, with the Temperature/Humidity sensors DHT11, DHT22 and LCD1602, without I2C possibility. There were a lot of cables to connect, we will try out this time to use a LCD with I2C bus connection as it uses less cabling (wiring)!

This tutorial shows how to use the I2C LCD (Liquid Crystal Display) with the ESP32 using Arduino IDE. We’ll show you how to wire the display, install the library and try sample code to write text on the LCD: static text, and scroll long messages. You can also use this guide with the ESP8266.

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.

How to connect and program the Geekcreit 0.96 inch 4 pin white I2C OLED module with Arduino. OLED display based on a SSD1306 OLED driver IC.

In this tutorial a 0.96 inch monochrome OLED display from Geekcreit is connected or interfaced to an Arduino. Libraries are then installed and some example programs run which show how to use the display in an Arduino sketch.

The display connects to Arduino using only four wires – two for power and two for data, making the wiring very simple. The data connection is I2C (I²C, IIC or Inter-Integrated Circuit). This interface is sometimes called TWI (Two Wire Interface).

At the very lowest level, the Arduino Wire library is used to communicate with the display. Libraries are available that make it easy to start using the display right away to display text and graphics. These libraries are installed in this tutorial.
