OPTO PLUS LED Corp. has launched an RGB 7-segment display with a built-in driver IC, fully compatible with Arduino. Traditionally, controlling a 7-segment display with Arduino required additional ICs and complex circuits alongside coding. This often made the process cumbersome for users.
This new product integrates all control components into a single module, greatly simplifying the design. With the built-in control IC, users can easily write control programs using open-source code, eliminating the need for extra circuitry. This makes controlling RGB 7-segment displays simpler and more convenient.
Appearance of an Arduino-compatible RGB 7-segment display
The Arduino-compatible 0.56” RGB 7-segment display with a built-in driver IC has the same exterior dimensions as a standard 0.56” 7-segment display. The key difference lies in the reduction of external pins, from 10 to 4, thanks to the built-in single-wire control LED driver IC.
This integration simplifies the control of the 8 LEDs within the display, reducing the need for external circuitry. Below is a size comparison between a standard 0.56” 7-segment display and a coin, along with a simple appearance diagram of the Arduino-compatible 0.56” RGB 7-segment display with the built-in driver IC.

Internal circuit of an Arduino-compatible RGB 7-segment display
The internal circuit of the Arduino-compatible RGB 7-segment display is composed of two main components: eight RGB LEDs and a control IC. The control IC connects these LEDs into a single-wire control interface, similar to the cascading method used in LED strips. It transmits brightness and color sequence data, enabling precise control over the brightness and color of the LEDs.

Wiring the Arduino-Compatible RGB 7-segment Display with Arduino
The Arduino-compatible RGB 7-segment display requires only three connection wires: connect DI (Data In) to Arduino PIN6, and VDD and VSS to Arduino’s VDD and GND, respectively. The DO (Data Out) pin can remain floating (unconnected), and the display will function normally without needing to connect it to any pin.

Demo and Demo code for Arduino-compatible RGB 7-segment display
Currently there are two demo videos of Arduino-compatible RGB 7-segment displays, as follows.
These two groups of Demos use similar demo codes to write programs, mainly using Adafruit’s Neopixel.h library to write programs. The simple Sample code is as follows.
