    Default A nice Current limiting Resistor calculator for leds

    decided to dive into this area and while scouring the net for designs and help on building my project and having no idea on resistance etc i found this little calculator.

    now i know it may not be much help to most but to me was a god send as i need to see to understand after that i remember

    All you do its tell it the details

    eg: parallel - power source - led voltage - led MILLIAMPS - led numbers

    and wolla the right resistor to use is shown.

    i love google

    I love it, you should see me i use 3 sheets of paper to do my calculations and I still get it wrong, but not any more
    When you do things right, people won't be sure that you have done anything at all
