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.

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
Great learning tool!
I am currently taking an electronics class and this is a perfect way to help memorize the color codes. The colors and values are all laid out in one screen. Thanks for making this app and offering it for free!
With Family Sharing set up, up to six family members can use this app.
