Expand Mobiflight Outputs with a Shift Register | 32 LEDs Using Only 3 Arduino Pins

Expand the output capability of your Arduino Mega in Mobiflight using shift registers to control up to 32 LEDs with only 3 Arduino pins. This step-by-step tutorial demonstrates the complete process of setting up, configuring and interfacing the hardware and software needed for some B737 indicator lights in Microsoft Flight Simulator 2020. Featured hardware includes the FlitePal Interface Solutions LED Driver Board (green board) and Shift Register Output Expander Board (black board). https://flitepal.com/home/5-mobifligh... https://flitepal.com/home/6-mobifligh...
