BlinkBox: Debugging Tool For Addressable LEDs

How often do you find yourself having to pause a project to make a test circuit or write some test code to find the source of a problem? Do enough variations of the same test and you’ll eventually make a dedicated test tool. That’s just what [Devon Bray] found himself doing.

[Devon] does a lot of work with addressable LEDs of different types and after much experience, created the BlinkBox, a dedicated test tool for addressable LEDs. It supports multiple LED chipsets, you can give it a count of the LEDs you want to light up, and you can choose a test animation.  It even writes your settings to an EEPROM so you that don’t have to repeat yourself when you next turn it on.

He’s also done a very nice job packaging it all up, creating a 3D printed case, using backlit buttons for working in the dark, and even added a contrast knob for the LCD screen. Kudos to him for all the effort he’s put making this polished. Everything you need to duplicate it is available on his webpage, along with the schematic for the curious. Watch it in action, or just admire his handiwork in the video below.

We couldn’t find any similar hacks here on Hackaday, but here’s a nifty LED tester that’ll also tell you which resistor value to use.
