Generic Trim Wheel

thingiverse

I created a side project, 737 yoke hat switch inset, available here, as I wanted to utilize Arduino's spare pins for a trim wheel, additional rotary switches and buttons. I never found satisfaction with Saitek Cessna trim wheel, so I decided to do it in a more simple yet functional way. In my simplified and generic cockpit, I also lacked 737 EFIS minimums rotary, so I opted to add two such switches with buttons and an additional button as I had enough space on the case. The specific outline of the casing follows GoFlight TQ6 throttles, which are positioned to the right of the trim wheel. The wheel itself was designed by AlbEagle (https://www.thingiverse.com/thing:2806090) and I printed it as is. Three holes were later drilled into the casing, 8mm in diameter at the bottom for wiring and 2x 3mm at the back for mounting.

Arduino Leonardo was used with the sketch tailored and modified from joystick library and gamepad example.
