Constrain Function for Negative Numbers

So that I could have a deadband

See

Adding a dead zone to a analog imput on arduino Leonardo

Joystick.setXAxis(map(analogRead(A3),0,1023,-127,127)); Rather than directly using the built-in 'map()' function you could define a custom function: int readAxis(byte pin) {   int v = analogRead(pin);   if (v < deadRangeLow)     return map(v ,0, deadRangeLow, -127, 0);   if (v > deadRangeHi)     return map(v, deadRangeHigh, 1023, 0, 127));   return 0; } Then you can just use: Joystick.setXAxis(readAxis(A3)); If you ever need to change the mapping you only need to do it in one place.

Everything you are doing here is simple logic or maths. And anything you can do to be able to figure it out will not be time wasted.
