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 the 5V power supply, the original state X, Y readout voltage of 2.5V or so, when pressed with the direction of the arrow, the read voltage values ​​with increasing, up to5V ; opposite direction of the arrow pressed, the readout voltage reduction , a minimum of 0V .
