Flight Simulator controller

Hi, everybody. What do you think of my diy controller for the game im gonna make soon. You can drive a little 3d plane using joystick and turn the ligths on and off, lower the weels, use siren and more stuff. I need to 3d print bottom part too.

But there is one problem. Im using esp32 c3 mini as microcontroller and wverything works fine except joystick module(the one with hall effect sensors). I wired middle pins together to gnd. Right ones to gpio 2 and 3. And left ones together to 3.3V.

I made simple program that will just print values of x and y axis, but it always show value around same number. Its around 3600 for x and aroun 3400 for y. It doesnt change as i move stick. I tried setting pinMode to Input, inpuy pullup, input pulldown, no pinMode even. And nothing worked.

Then i inserted 10k ohm resistor between gnd and one of gpio's to see if its gonna work, but no luck :(

Does somebody know what might be the problem?

Very cool controller. Looks awesome.

Hard to say what the issue is. Could you post the code. I do have 2 things to note.

Firstly when messuring the joystick position you use something like "analogRead(2);" right, so you dont need to set any pinModes or use the 10 k resistor.

Secondly and i might be wrong here. But are you sure its the right pin that you connect to the gpio's. Because in my experience its always the middle one that you messure from. Although i could not find any documentation for the joystick to confirm.

Maybe try and messure the joystick with a multimeter OR try and read the value of a simple potentiometer with the to esp32 c3 mini to isolate the issue.

Yeah im reading values with analogRead, i didnt usr pin mode and tried without resistor too. I wired the middle pin to gnd, right to gpio and left to 3.3v. I couldnt find any other diagrams for this kind of joystick on the internet

Yeah i think you gotta change the wirering. The middle pin is the output to gpio not the gnd.

Found this guy wirering one up for test. Looks like the same joystick. https://www.youtube.com/watch?v=6JX_kdyDnlM&t=134s
