I gives wrong results. It is just printing values without touching the joystick.
I added 1k resitor, restarted and it is still throwing values on the monitor. I am now thinking I make have connections wrong or the joystick is not working. I don't know exactly how to test it.
I would use the internal pullup resisitors by setting the pinModes to INPUT_PULLUP and add a 0.1uF ceramic cap from the input to ground. The cap will bypass noise to ground and provide some hardware debounce.
If the readings are still not right, you may need stronger pullup. Stsrt with 10K external pullup and go lower from there. 1K minimum.
Those resistors are not doing anything, they need to go from the joystick pin to ground. You have both sides of the resistor on the same rail. It’s as though the resistor isn’t even there.
Correction: you have a few mistakes… the Arduino needs to be connected to the ground rail along with those stepper modules. They need a common ground otherwise you will get proper readings or functionality.
I highly doubt that 9V battery will be enough for both servos. I don’t know if it’s even enough for one.
If this is what you mean..it is still giving the same results random values. Even a common ground. At the moment my focus is on getting the joystick to read when it is moved
I am very sorry. I did rearrange the pins but posted the old code. The code is the same I only changed the pins. My question now is, is this a digital joystick or analog. I got from AliExpress a long time ago not sure it came with a datasheet. I am confused right now because I can't find any helpful or working information online.
