====== Mini-Tiller Box ======

Created a 3D Printed Box with a small (about 40% actual size) 737 Nose Gear Tiller, a miscellaneous slider linear potentiometer, and 2 misc. push buttons. 

This box has a Arduino Micro Pro in it, which is one of those which looks like a Joystick to Windows, if the right software library is loaded. Initially, I wrote code to read the Tiller (which has a Hall-effect sensor and 2 magnets) and via the Arduino Interpolation code, converted the range of motion to 0 - 1023. 

Later on, I added 2 LEDs, and using the MobiFlight system, flushed the sketch to convert the Micro Pro to a MobiFlight board. This allows the device input Tiller and Slider, the 2 push buttons, and the 2 LEDs to all work with MSFS 2020.

This is using MobiFlight 9.6.

^Arduino Pin^Function^
^A0|Hall effect - Tiller|
^A2|Linear Potentiometer - Slider|
^2|Push Button 1|
^4|Push Button 2|
^5|LED White|
^7|LED Red|

The trick was to get MobiFlight to properly read and interpolate the Tiller. Initially I was trying to output values in the -16384 to 16384 range, but the Event I am now using requires 0 to 1023 range. I kept getting a UInt32 error being outside the range. "U" is for unsigned so 0 and positive only.

^Event^Description^Range^
^STEERING SET|Nose Gear Steering|0 - 1023|
