Resistor Color Code Calculator, developed by CRUX, is a free educational and reference application available on Android. This user-friendly tool helps users to easily calculate the resistance value of a resistor by providing its color code. The app supports three, four, five, and six bands resistor and can also determine the SMD resistor value.

The app has a simple interface and provides real-time calculation results. The color bands can be easily selected by tapping on the corresponding color buttons. The app also includes a list of common resistors with their color codes, making it easier for users to identify them. There is no need to register or log in to use this app.

In addition to the Resistor Color Code Calculator, the app also provides links to other useful electronics calculators, IoT, robotics learning, and robot control resources. Whether you are a student, hobbyist, or professional in the field of electronics, this app is an essential tool to have in your arsenal.
