5 pin two way Arduino PS2 joystick game controller modules / Joystick Module

Arduino PS2 joystick game controller module Joystick Module

PS2 joystick game controller module standard interface and electronic building blocks 2.54mm pin interface leads.





Cross rocker as a two-way 10K resistor, with the rocker in a different direction, tapthe resistance with the change. This module uses 5V power supply, the original state of X, Y read voltage of 2.5V or so, when pressed with the direction of the arrow, asread out voltage increases up to 5V; press the opposite direction of the arrow, readvoltage reduce the minimum is 0V.
