Thumb slide joystick
This is a resistive analog joystick, very similar to those found on the PSP1000. These compact joysticks are different in that they have a very interesting ‘slide’ feeling. From our customer regarding pinouts: With the nub up and facing you, and the pins on the bottom away from you and pointing towards your chest, from left (pin 1) to right (pin 4). Please note that pin 4 is the one closest to the two screw/mounting holes. When connected to an Arduino, You will be able to get a range of about 128 to 775 on each axis, with enough consistency to check if it’s at -x, center-x, +x, and -y, center-y, and +y.
