Worked great for me. When I click on the link it opens with Firefox. I learned a few things just using the software. Thanks!

Subject: [TriEmbed] LED resistor/Ohm's law calculator

 

I wrote a little tool to compute current limiting resistor values for LED's in series. 
For many on this list, this is a pretty basic calculation, but I get asked about this type of setup often enough, and thought it would be fun to write a tool that calculated the resistor needed. (It can also calculate the other components of the Ohm's law equation as well). I had started this one a long time ago, and the recent Triembed Ohm's law talk, among other things, inspired me to finish it and finally put it up.

Feedback is appreciated. I still need to do some validation on the inputs, it will let you put non-sense values in, such as negative numbers, etc.


I'd love to make a bunch of little tools like this on my site, though they do take a non-trivial amount of time to put together.
