I have a PS2 joystick for my arduino to control the throttle of a drone. But I am having trouble with the sensativity of the joystick. When I move it about 30% of its range in any direction the analogread gets to maximum 1023. I have about 70% of its range left and it is kinda "dead" after the 30%. How can I make it reach all the way to the top?
Best regards Max
How is it wired, what code are you using to test with, what Arduino are you using?
I am using an arduino Uno. It is wired:
VCC > 5V
GND > GND
XAXIS > A0
Thats it, the code is just analogRead(A0) and the serial.print it.
Are you sure the potentiometers on your joystick do not have a physical dead zone?
I have seen cheap joy pots that have a undeniable and unfixable deadzone, sometimes substantial. They are worthless for real flight control.
Measure the resistance as you move the pot and see.
I measured the resistance and the problem is that the joysticks are probably garbage. Purchased them for about 1.5$ each. I will have to get some new ones
Do you have any recomendation on a good flight controller joystick?
because I wanted to find something like this
which is neither where I buy stuff nor exactly the unit I did purchase, but this is a real joystick that is almost identical.
I use the $10 - $15 PS2 controllers and they provide a good range > 95%
If you buy a port you can test them in a non-destructive manner and return any that are junk.
Got mine on Amazon.
technically deadzone is when you move your joystick and nothing happens until you move it more
