Im working on a EMD Project for class and my idea was to create a warning light system for my airboat. Im running a small block chevy motor with Faria gauges and sending units like the one below
My idea is when the motor gets up to a temperature of 220 it will trigger a yellow led then when it gets to 230 have a red led come on and if it gets to 240 have it flash the red led. Then maybe do the same type of thing for oil pressure and voltage. So this way I don't have to stare at my gauges while driving the boat.
How would I go about wiring something like this and what all would I need to make it work? This is my first time using an ardino but have programmed with matlab in the past. Im not sure where to find more information on the seding units and how to make them compatible with my arduino uno? Any help would be much appreciated. Thanks
