### Project 34 Joystick Module

**1. Introduction**
Lots of robot projects need joystick. This module provides an affordable solution. By simply connecting to two analog inputs, the robot is at your commands with X, Y control.

It also has a switch that is connected to a digital pin. This joystick module can be easily connected to Arduino by IO Shield.

**4. Sample Code**

```c
int JoyStick_X = 0; //x
int JoyStick_Y = 1; //y
int JoyStick_Z = 3; //key

void setup() 
{
  pinMode(JoyStick_Z, INPUT); 
  Serial.begin(9600); // 9600 bps
}

void loop() 
{
  int x,y,z;
  x=analogRead(JoyStick_X);
  y=analogRead(JoyStick_Y);
  z=digitalRead(JoyStick_Z);
  Serial.print(x ,DEC);
  Serial.print(",");
  Serial.print(y ,DEC);
  Serial.print(",");
  Serial.println(z ,DEC);
  delay(100);
}
```

**5. Result**
