Using a Javelin to measure voltage

Hi there, I'm new to the javelin, but not new to Java. Part of the program I'm writing needs to read voltage levels. Will I need some kind of A/D converter for this, if so, is there one that is recommended for use with the javelin? Thank you! [noparse]:)[/noparse]

    If 8bit resolution is sufficient you can use the ADC virtual peripheral. That only
    requires 2 resistors and a capacitor for a 0-5V input range.
    See the javelin manual for ADC circuit.

    regards peter

    wow, thank you so much! I'm reading about it in the manual now, 8 bit resolution will work for exactly what I need. Thanks again Peter! smile.gif
