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.

  • 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.
  • Game joystick
