Hardware Description

Pinout

• GND - Ground connection
• +5V - 5V connection
• VRx - analog voltage value between 0V and 5V giving you the relative x position
• VRy - analog voltage value between 0V and 5V giving you the relative x position
• SW - pushbutton switch, click in to press

 

Software Description

• Use analogRead() to determine the x and y position of the joystick.
  • Remember: analogRead() returns a value between 0-1023
  • The midpoint is ~512.
• Use digitalRead() to determine whether or not the switch is pressed.
  • Configure pin like so: pinMode(SW, INPUT_PULLUP)
  • Switch is pressed when digitalRead(SW) == LOW
