you need not invent. it is already there
are you powering the servo from the Arduino ?
How much current do you need?
I have fixed the button, that is all good now, it works and doesn't short circuit my Arduino
I have 3 servos that are in my circuit.
For the moment I am re-soldering the circuit because it looks really bad at the moment.
Edit: also because some of the tracks on the Vero board have started coming off, so I'm getting a new Vero board.
the question is where does the Servos' power come from?
They get the power from the Arduino itself. A jumper goes from the 5V to the + on the breadboard and then jumpers go out to the servos and joystick
It’s likely not your joystick issue but it might create a situation where too much current is drawn from the servos and the voltage of your arduino board drops possibly creating stability issues with the board or impacting the 5V reference expected by the analogRead
In general it’s best to power servos separately from the arduino
