Microduino-Joystick is a joystick sensor, which can detect horizontal displacement of a joystick. 
It can return analog values of X-axis and Y-axis via the analog port, whose range is between 0-1,023. 




==Features==
*With X- and Y-axis directions. 
*Small and beautiful  

==Specification ==
*Electrical specification 
**Operation voltage: 3.3V~5V
 **Input device 
*Tech parameters 
**Pin description: GND, VCC, signal 1 output and signal 2 output. Since the output signal is simulated, you can use analog port to detect (A0-A7) by connecting to the pins including A7/A6,A3/A2 and A1/A0 of Sensorhub. 
**Analog input 
*Size 
**Size of the switch: 17mm*17mm，
**Size of the board: 20mm*24mm
**1.27mm-pitch 4Pin interface connects with Sensorhub.

==Document==

*Schematic: '''[[File: Microduino_ Joystick.Zip]]'''


==Development==
===Preparation===
*Make sure you build Microduino IDE or refer to: [[Microduino Getting started]]
*Core selection 
**1. Adopt [[Microduino-CoreUSB]] or [[mCookie-CoreUSB]] as the core. 
**2. Adopt [[Microduino-Core]] or [[Microduino-Core+]] as the core plus [[Microduino-USBTTL]] as the program download module. 


===Program===
<source lang="cpp">

void setup() {
  Serial.begin(9600);    //Serial port initializing 
}

void loop() {
  int sensorValueX = analogRead(A0);      //X-axis input 
  int sensorValueY = analogRead(A1);      //Y-axis input
  float voltageX = sensorValueX * (5.0 / 1023.0);
  float voltageY = sensorValueY * (5.0 / 1023.0);
  Serial.print(voltageX);
  Serial.print(",");
  Serial.println(voltageY);
  delay(50);
}
}
</source>

===Hardware Buildup===
*Stack all modules firstly, then connect Microduino-Joystick with Sensorhub to A0/A1 port with a wire.  
Please refer to: [[Microduino-Sensorhub]]

Please refer to: [[mCookie-Hub]]
[[file:mCookie-sensorhub_Analog.PNG|thumb|400px|center]]
*Connect the core, Sensorhub and LED to a computer with a USB cable. 
*Select the right board and COM port, compile and download. You can refer to [[AVR Core：Getting started]]
[[file:upload.JPG|thumb|800px|center]]
*Choose the right port number from Tools→Serial Port in Arduino IDE after compiling and then download program.  
*Open the serial monitor after download and you'll see analog quantities on the direction of X-axis and Y-axis displayed on the console. When the joystick is in the middle, it displays around 2.5 on both X-axis and Y-axis.  
==Application==
You can simulate mouse movement and other displacement sensors as human-computer interaction input.
