1 Introduction
Makeblock Orion is an easy-to-use mainboard based on Arduino Uno with improvements for education. It provides eight RJ25 ports to connect to all the other Me series modules with color-labels, can save you from horrible pin-wiring and help you focus on inventor amazing projects. Makeblock Orion supports most of programming software (Arduino / Scratch / ), and we offer the customized graphical programming software (Scratch for Robot / Makeblock App).

4 Interface Description
There’re 8 RJ25 connectors in total. The tags on the connectors have 6 types of color. Check the following table for the function and attribute of each connector.
Tag ColorFunctionTypical Me Modules
Red represents the output voltage of Vin (6-12 VDC), which is the power input voltage. Generally, it is connected to some voltage driver module with 6-12V.

5 Usage
Connect the Makeblock Orion and computer with micro-USB cable first. The first time you use Makeblock Orion ,you need to install the
USB interface driver.Makeblock Orion support up-computer and mobile device control.(Arduino IDE/Scratch For Robot/Makeblock App control).
The programming guide link of each software is as follow:
(1) Arduino IDE:
http://learn.makeblock.cc/learning-Arduino(2) Scratch For Robot:
http://learn.makeblock.cc/learning-scratch(3) Makeblock App:
http://app.makeblock.cc6 Programming Guide
1. Here’s an example to show you how to programming the buzzer of Orion in Arduino IDE:
A) Connect the Makeblock Orion and computer with micro-USB cable first.
B) Create a file in Aduino IDE, and write the buzzer control sketch as follow:
#include
#include
#include
void setup()
{
}
void loop()
{
buzzerOn(); //turn on the buzzer
delay(50); // wait 50 milliseconds
buzzerOff(); //turn off the buzzer
delay(50);
}
If you got any error information, please check if there is a grammar mistake in your code.
C) Upload the program
D) After the uploading is successful, the buzzer will sound. If it doesn’t work, please check if the buzzer switch on the board is TURN ON.
2. Here’s an example to show you how to programming Me 130 DC Motor in Arduino IDE
A) Connect the Makeblock Orion and computer with micro-USB cable first.
B) Connect the Makeblock Orion and Me 130 DC Motor as below:
C) Create a file in Aduino IDE, and write the buzzer control sketch as follow:#include
#include
#include
MeDCMotor motor1(M1); //130 DC Motor can connect to the motor interface(M1 or M2)
uint8_t motorSpeed = 100; // value: between -255 and 255.
void setup()
{
}
void loop()
{
motor1.run(motorSpeed);
delay(2000);
motor1.stop();
delay(100);
motor1.run(-motorSpeed);
delay(2000);
motor1.stop();
delay(100);
}
If you got any error information, please check if there is a grammar mistake in your code.
D) Upload the program
E) After the uploading is successful, you can see the motor rotating in clockwise direction 2s, pause 100ms, rotating in anticlockwise direction 2s, pause 100ms.
3. Other Demo Code
There are some demo code of the Me series electronic modules from the File > Examples > MakeBlockDrive. You can use the demo code from
Makeblock Library New or
Makeblock Library Old to get started play the Me series electronic modules. We recommend that you use the latest code to get our best service support.
7 Power supply
Kindly advise to power the board by connecting 6V-12VDC to DC Connector of Makeblock Orion. Otherwise it will power off for PORT 1 and 2. There’s a switch on the board for controlling the power ON/OFF.
