1 modul PS2 Game Joystick Arduino Compatible

Product Description

• Arduino standard 3 pins
• 2.54 standard pins

The joystick is a double direction 10K potentiometer, the resistor value is changing when joystick direction changes. This module use 5V power supply, reading value around 2.5V at the raw condition, value will increase when the arrow go down till maxium 5V; the value will decrease when the arrow go other direction till 0V.
