The Use of Joystick Sensor

Outline The Microduino Joystick sensor is two analog output devices in one. There are resistors on the X-axis and Y-axis that each output an analog value corresponding to the position of the joystick on that axis. This sensor is great for controlling projects, especially ones that move. Specification Electrical Specifications Analog Output Device Analog Output: 0-1023 (with Microduino Core modules) Technical Specifications Analog Output Corresponding to X and Y-axis displacement Dimensions Switch: 17mm x 17mm Board: 20mm x 24mm Connection Interface Pins: Signal 1 (X-Axis), Signal 2 (Y-Axis), VCC (power) and GND (ground) Must be connected to analog capable ports (A0-A7) 400px Development Equipment Module Number Function mCookie-CoreUSB 1 Core board mCookie-Hub 1 Sensor pin board Microduino-Joystick 1 Joystick sensor Other Hardware Equipment One USB cable 600px Preparation Setup 1：Connect Microduino-Joystick and the Hub 's A0 and A1 analog ports. 600px Setup 2：Stack the CoreUSB, Hub and Light together and then connect them to the computer with a USB cable. 600px Experiment: Detect Analog Joystick Value Open Arduino IDE and copy the following code into IDE. #define Pin_X A1 #define Pin_Y A0 void setup() { Serial.begin(9600); //Serial initializing pinMode(Pin_X,INPUT); pinMode(Pin_Y,INPUT); } void loop() { int sensorValueX = analogRead(Pin_X); //X-axis input int sensorValueY = analogRead(Pin_Y); //Y-axis input Serial.print("ValueX:"); Serial.print(sensorValueX); Serial.print(","); Serial.print("ValueY:"); Serial.println(sensorValueY); delay(100); } Select the right board from Tools→Serial Port in Arduino IDE and download the program. After the download, you can open the serial monitor. The displayed note reflects the current displacement analog values on both X-and Y-axis. Result The right shift value decrease on the X-axis, close to zero while the left shift value increases and gets close to 1,023. The top shift value decrease on the Y-axis, close to zero while the downward shift value increases and gets close to 1,023. Program Debugging Use“analogRead(XX);” to read sensor's input analog value and judge the displacement on both the X-axis and Y-axis. Application To control object movement in two-dimensional space.
