Overview
Me 7-Segment Display-Red module adopts a 4-digit common-anode digital tube for displaying the numbers and a few special characters. The module can be used in the robot project to display the data such as the speed, time, score, temperature, distance, etc. It uses specific chip with LED drive and control, so that the digital tube can be controlled easier. Makeblock also provides Arduino library for easy programming to allow users easily controlling the digital tube. Its blue ID means that it has a double-digital signal port and needs to be connected to the port with blue ID on Makeblock Orion.

Pin definition
The port of Me 7-Segment Display-Red has four pins, and their functions are as follows:
Wiring mode
● Connecting with RJ25
Since the port of Me 7-Segment Display-Red has blue ID, you need to connect the port with blue ID on Makeblock Orion when using RJ25 port. Taking Makeblock Orion as example, you can connect to ports No. 3, 4, 5, and 6 as follows:
● Connecting with Dupont wire
When the Dupont wire is used to connect the module to the Arduino UNO Baseboard, its DIO and CLK pins should be connected to digital ports as follows:
Guide to programming
● Arduino programming
If you use Arduino to write a program, the library Makeblock-Library-master should be invoked to control the Me 7- Segment Display-Red module. This program can make the Me 7-Segment Display-Red displaying 15 digits of number and moving the characters 1, 2, 3, 4, 5, 6, 7, 8, 9, A, b, C, d, E, and F from right to left through Arduino programming.
