文件:Microduino-Joystick.jpg Microduino-Joystick 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. 文件:Microduino-Joystick rule1.jpg 600px Document Schematic: 文件: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 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); } } Hardware Buildup Stack all modules firstly, then connect Microduino-Joystick with Sensorhub to A0/A1 port with a wire. Please refer to: Microduino-Sensorhub 文件:Microduino-sensorhub Analog.PNG 400px Please refer to: mCookie-Hub 文件:MCookie-sensorhub Analog.PNG 400px 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 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.
