PS2 joystick joysticks standard interface module electronic building blocks and 2.54mm pin interface leads .
Phillips is a two-way rocker 10K resistor , with the joystick in a different direction , tap the resistance vary.
This module uses a 5V supply , the original state X, Y readout voltage of 2.5V or so, when pressed with the direction of the arrow ,
the readout voltage values with increasing , up to 5V; press the arrow in the opposite direction , the readout voltage reduction , a minimum of 0V.
