Hello, im planning on using a 10" lcd instead of all the analog/mechanical gauges in the dashboard. No fancy graphics, just bars and numbers that show the sensor readings. First sensor name, for example ECT (engine coolant temp) OIL (oil pressure), then bar showing the value and after bar number showing value- Example ( ECT bar 85 C). I understand that the raspberry need a analog-> digital converter. And the sensors will be connected to the analog inputs.
How are the sensors electrically connected?
Other wire to ground and other to analog input?
Or other wire to voltage feed (5v dc?) and other to analog input ?
All sensors are linear resistance, so programming should be relatively easy.
Im a noob with programming raspberry but im familiar with electric stuff.
