Struggling With x3 Bigger Analog Signals and Fluctuating Digital Signal (Joystick, Nano ESP32, I/O Shield)

Projects General Guidance

Hi,

I'm trying to get a joystick to work with the latest Arduino Nano ESP32 on a I/O shield.

I'm really new to Arduino without any electrical background.

I managed to get analog readings of the joystick wile attached to USB-C but the readings are odd.

I'm expecting A0 and A1 to be around 500 in their neutral position, but instead they are approx 3000 when resting (They get to 0 or 4000 when the joystick is pressed on opposing directions).

Similarity, the joystick press (D2) is fluctuating between 0 and 1 when not pressed, but 0 when pressed. Was hoping it would be either 1 or 0 in some stable state.

Here is the setup.

I've spent hours on this. Struggling.

Can anyone help?
Best,
Jakub

You need to add the most important things…
schematic, and code
