Calculate resistor color codes with this handy reference app. The app is useful for the maker, engineer, student and arduino or raspberry pi tinkerer when working with electronics.
Supports 4 and 5-band resistors!
The industry standard color-code is used to identify the resistance value of resistors used in all kinds of electronics.

Great - But Needs Precision Option
Extremely helpful for standard resistors with four color bands. Would be nice to have a 5 band option.
I would pay if the app allowed the camera to ID the colors, if fast and reliable.
Wow, just perfect
Simple is as simple does, this app translates the resistor color codes to numeric form on one easy-to-use page; I love it.
Caution: you really need a reliable multimeter to verify that the resistor you have actually measures correctly, as it may have been overheated or otherwise incorrect.
Your green colour look so poor can you make it more brighter please
