Jul 7, 2018 · If you want to use more than one, you need to modify the i2c address of your display (consult your display datasheet for this) and use the u8g2.setI2CAddress command in setup () procedure for the second u8g2 object.

To simplify the assembly process I have developed a LED Dipslay Module for multiple purposes using simple and common components in the Arduino's world. With this module you can work with dot matrix with dual color LEDs in two standard sizes (bigger and smaller) and also you can control 7 Seg x 4 Digits display that are very common and easy to ...

Jun 23, 2014 · Both OLED's have address jumpers so I can address them separately (0x3C and 0x3D). I've test run both the Adafruit lib and the u8glib which I can use to display all my data on a single display, but how do I setup two displays based on the addresses above?

To get multiple screens we will create a variable called "page_counter" and the default value is 1 (first page or home page). int page_counter=1 ; //To move beetwen pages. With the buttons we add or subtract 1 and move the counter from 1 to 3 (total of pages).

Jan 4, 2024 · Learn How to interface a 74HC4051 8-Channel Multiplexer Module with Arduino. using 74HC4051 Module example code, circuit, pinout, library. This high angled picture does show it in limited quality. best regards Stefan. The oled that im working with doesn't have this option, it's an sh1106 128x64.

Mar 12, 2025 · One of the most efficient ways to control a dot matrix display with an Arduino is by using the MAX7219 LED driver chip. This powerful integrated circuit simplifies the process of controlling multiple LEDs by reducing the number of pins required for communication.

In this example I will show you how to multiplex a 7 segment LED display from a microcontroller such as an Arduino without placing too much load on the microcontroller pins as I have seen in some other examples - not necessarily on this site I might add!

Aug 4, 2010 · We Can Easily Run Two to Four 16×2 LCDs On Arduino UNO. In This Article, We Will Supply Same Code and Diagram For Running Multiple LCD Displays On One Arduino UNO.

Oct 4, 2024 · Learn how to connect and interface multiple I2C LCDs (16x2 and 20x4) with Arduino. Configure addresses, wire connections, and display data on multiple screens easily.

Jan 10, 2019 · My first experiment was to try to control 4 OLED displays (all having the same I2C address) using only 5 GPIO lines (4 SDA + 1 SCL). I chose the Arduino Pro Micro (aka Leonardo) as a good board for this test. As you can see in the image above, it works.
