http://hackaday.com/2012/01/26/analog-joypad-for-your-retro-pc/
so I went to sell second hand store for bought thumb of joystick.
I follow it and investigate. but I was failed. so I want to ask everyone.
I use 10K trim pot and add some capacitors but no matter how to adjust it won't permanent position.
schematic diagram I have a little confuse. can you tell me how to connect gnd and 5v.
I measurement thumb stick resistor value around 8.5k. but double thumbs of joystick value 120k. so it won't adjust and add trimpot.
how to create this thumb stick. I want to make it right. hope everyone can solve it and teach me. thx
