I am finally done with my multi-gauge. I built the temperature sensors using the one wire digital sensors from Dallas. These are cool because the temperature is converted to a digital signal at the point of measurement, and using some software trickery, you need only one wire for as many sensors as you might need with no signal loss due to wire length or the possibility of interference or crosstalk from other sensors and signals
The pressure sensors are 150 psi sensors that I got from China. They are not your standard oil pressure sender that varies resistance. These output a 0-5v signal much like the AEM sensors at a fraction of the cost. Ideal for the Arduino and easy to calibrate and program. I have no doubt that they are durable because I dropped them like 20 times and they still work fine.
Here's the secret behind this whole thing... 4D Systems display. So no I am not some programming genius. :lol: All of the objects are place using powerful WYSIWYG software so it is as simple as selecting an object you want to display and placing it where you want it to show, Then editing it to your liking and assigning it a function. Then it is as easy as calling that function in the Arduino. It's brilliant!
Really any idiot can do this as I am proof of that. :tup:
