LCD and an arduino

  1. Jul 26, 2014 #1
    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,

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

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