How It Works

The horizontal and vertical axes both work the same, so we only need to look at one of them to see how the whole thing works. Let's look at the horizontal.


The PC port can accommodate two joysticks. You can easily create a duplicate circuit to use a second digital stick with the PC. The table below lists the pins for stick 2 equivalent to the stick 1 pins in the schematic.

Function Stick 1 pins Stick 2 pins
+5V 1, 8 9, 15
GND 4, 5 12
Horizontal 3 11
Vertical 6 13
Button A 2 14
Button B 7 10
