Hi all, I have a project that I would like help with - actually more than help as I have no electronics training.
I'd like to use a pressure differential transducer like this: **broken link removed**
to drive a 10 LED display. The circuit will illuminate more LED's as the pressure differential equalizes. I poked around enough to think this could be done with a LM3914 but I don't have the knowledge to take this project any further. I imagine I would need some kind of voltage regulator as the power source for this will be an automobile type battery/charging system. I would also need a way to adjust the circuit to define the low and high pressure differential ranges. Having an audio alert when 3 or less LEDS are lite would be and added bonus. Any pilots out there want to guess what this device would be called?
Thanks so much in advance.
