Resistor Color Code is a free Android application designed by Adriano Moutinho, specifically for electronic circuit designers. This application provides a comprehensive tool that helps users determine the value of a resistor by just looking at its color code. The interface is user-friendly and includes a graphic interface to show 4, 5, and 6 color bands. The application also includes the tolerance value, making it a complete solution for resistor value determination.

Resistor Color Code is a stand-alone application, but it is also included in the complete version of Electronic Circuits, which offers additional calculations for BJT and FET. The application is an excellent reference tool for professionals and students alike, who need to determine the value of a resistor quickly and efficiently.
