Are you color blind? Then it would be hard for you to recognize the resistor value while working on projects. Rich Olsan from nothinglabs developed a cool iPhone application for you guys which helps identifying the resistor values through its camera. All you need to do is install application on your iPhone and follow these steps.
Using resistor ID is easy:
1. Take a photo of a 4-band resistor using the app
2. Drag the numbered bars over the corresponding resistor bands
3. Resistor Photo ID provides you with the resistance and tolerance of the resistor!
If for any reason Resistor Photo ID doesn’t detect the correct color for a band – you can easily override it.
