Resistor Color Code and Light Emitting Diode Ca...

Works well and is free!

Works just how it should, could be prettied up a little bit, but very handy and quick to use for anyone getting into electronics!

I'm an electronics geek and this app is a great reference tool when I need to identify a resistor's value. It's especially useful if you are trying to identify a blown resistor or one that is connected in parrallel with others since you can't just measure the resistance with a multimeter in these scenarios. I may be a nerd, but not enough so that I always carry a resistor color-code chart with me! But I do always have my phone. My only suggestion would be to include a help page explaining the usage of the LED function or better yet, change it so you can enter any 3 of the following and the fourth will be calculated: 1) input voltage, 2) LED nominal voltage, 3) LED current, and 4) resistance. Thanks for this very useful free app!
