Title: Real 737 Fuel Flow gauge and Arduino
Post by: 727737Nut on May 21, 2015, 05:03:27 AM

Finished up another project in my long list of projects for my 737-200 Sim. Got my 737 Fuel FLow gauges working using 2 outputs from a TeensyLC/Arduino. Basically I am simulating the output signal of a FF transmitter to the input of the gauge. Pulsing the 2 pins alternately at varying frequency. The toggle sw on the MIP to toggle between fuel used and reset wires straight to the gauge. Now I can fly it more like the real one as the pilots set power by the fuelflow as it was more accurate in the real plane.

Short Video of it being tested,
