[simpits-tech] Arduino victory!

[dabigboy at cox.net]

Well, this non C coding, Python welding cockpit builder has just achieved another little victory: I am driving a real Cessna OAT (outside air temp) gauge with an Arduino, from within Python on my laptop. I had to use a resistor to pull voltage down, otherwise even low PWM duty cycles overwhelmed the little temp gauge, resulting in a very poor resolution (basically the gauge would max out at a cycle of 24 out of 255 pulses). Calibration is not exactly perfect, but it's close enough for now. I think the serial comms was the hardest part! Working great now...more importantly, I am sending two pieces of data (temp and flap setting) and am able to keep them straight in the Arduino...yay!

Video to come soon.
