You don’t have to know much about electronics to at least be aware of the existence of resistors. If you’ve never seen one, it might be because you either weren’t looking for one to begin with, or you didn’t see it since they usually are very small.
To keep the boredom at a minimum, a resistor is an electronic component (a two-terminal component to be exact) that regulates the flow of electric current. They come in a wide range of colors (and for good reason) ranging from black, brown, red, to white, gold, and silver. That’s because they are very tiny and it’s quite difficult to print the resistance values on them – hence the colors.
If you’re just starting an electronics project and you’re not particularly familiar with resistance/resistor color codes, fret not – “there’s an app for that.” The apps in question range from mobile, online, and even desktop apps.
Color code is one such application, a GTK4 and Libadwaita desktop app that’s fully written in Python. It’s also free and open-source.
For what it is, it’s very good as it allows you to find out the ohm values and tolerances based on resistor color codes.
Color Code is a small WYSIWYG application. The way you interact with it is quite straightforward. You select the specific colors from four drop-down menus (the first digit, the second digit, the multiplier, and the tolerance values), and the app simply displays the results.
In terms of features, well, there aren’t many (not that that’s a problem). You’re provided with a quick copy function for the displayed value, and that’s about it.
Color Code is by no means an impressive app. Still, it’s a well-designed app in the sense that it gets the job done flawlessly, and that’s pretty much all that matters.
