Arduino & LCD Capacitor Voltage Project | Zig

[Ziggey]

Hey guys so I'm working on a project with an Arduino. I need the Arduino to read from a LCD to tell it what the voltage of a capacitor is. If the voltage is to low I would like it I switch the circuit on to charge the capacitors back up. Anyone know where a good starting point would be?

Thank you,
Zig.

How is the LCD getting the values to display?
IS there a way you could instead redirect this signal right to the chip?

Well I wanted to use something like this for the volt meter. http://www.ebay.com/itm/Digital-Voltmeter-AC-80-500V-Voltage-Measure-LCD-Panel-Meter-230V-110V-220V-/390895017063?pt=LH_DefaultDomain_0&hash=item5b03289c67

But I'm not sure if I can use that or if I would have to use the half divider code specifically for Arduino.
Thank you,
Zig

It would almost certainly be order of magnitudes simpler to use the chips built in AtoD than trying to read off of that LCD.

Ok well that is good to know. Thank you for your help!
