RE: Designing an Engine Oil Temperature Display Gauge Project

#14

Alain: Attached please find a circuit diagram that would work with a 3-digit 3-segment LED display, and able to read 2 independent analog channels (EOT and IAT), both scaled between 0 and 5V. Impedance is megaohm/ish. Display decoding is done by the MAX7219, analog read and conversion (along with all the pretty stuff) is via the ATTINY85 microcontroller (programmable in plain C). This entire thingy is very similar to my original "gadget", except for ditching the DS18B20 temp sensors, light sensor, and adding a second analog voltage input. Hope this helps.
