Arduino 56 Button Joystick 737 Gear Control

In this video we build a 737 Gear Handle for the Sim. This is a 3D Printed unit with all the parts additionally added below. Programming required for an Arduino Pro Micro as a 56 Button Joystick controller to interface additional switches beyond just the buttons for the gear handle. 3D print file I found and bought -- sorry could not find a free one. Switches I used: GC Electronics 35-842 Actuator: Simulated Roller Arduino Pro Micro =sr_1_4?keywords=arduino pro micro&qid=1559527170&s=gateway&sr=8-4 Has to be either a Pro Micro or a Leonardo -- needs the 32u4 for direct HID not work with other models. Sketch It is in the Video -- Youtube does not seem to like it added here do to bracket types used
