==Objective==

The course will show you how to simulate a compass in Processing by presenting the data of magnetic field strength detected by Microduino-10DOF module.

==Equipments==
*'''[[Microduino-Core]]'''
*'''[[Microduino-FT232R]]'''
*'''[[Microduino-10DOF]]'''

*Other Hardware Equipments
**A USB cable

==Schematic Diagram==

The HMC5883L magnetic field strength sensor of Microduino-10DOF will be available.

==Program==

Referring to compassMicroduino

compass_simulator

==Debugging==

Step 1：Building the hardware environment according to the schematic diagram, just like this:
[[File:compass_simulatorConnectionDiagram.jpg|600px|center|thumb]]

Step 2：Here is the code we need:

The code of the two ends (Processing and Microduino)

Microduino:

//The data of the magnetic field strength will be exported into the serial port to be displayed on Processing

void loop()
{
mag.getHeading(&mx, &my, &mz);
Serial.print(mx);
Serial.print(",");
Serial.println(my);
}

Processing:

//After getting the data of the first serial port, defining them or caching them if there is a new line // is always my Arduino, so I open Serial.list()[0].
// Open whatever port is the one you're using.
myPort = new Serial(this, Serial.list()[0], 9600);
myPort.bufferUntil('\n'); // Trigger a SerialEvent on new line

//Presenting the data obtained from Microduino on the screen in the form of curves with different color and then marking them

Function Description:

//Drawing a magnetic field pointer
arrow(int x1, int y1, int x2, int y2, color c)

//Judging whether can convert them into numbers
isNumeric(String str)

Step 3：Uploading the code and compiling them successfully.

Step 4：After the system goes smoothly, you can use a magnet to change the magnetic field and see if there is any change.

==Result==

There will be a simple compass displayed on the screen and the pointer will change along with the magnetic field. As follows:
