7-Segment ht16k33


I want to make a simple program with the 7-segment HT16K33 1.2 inch. We are using the program from this forum, but we have ran in to some problems. We are able to upload the program to our brainbox arduino, but we arent able to make the lights go on. If someone knows what the problem is or what we should do, please answer this question if u have any idea.


Arne and Wannes.

You have built something, but you don’t say what. You have some code but you don’t say what.

So all I can suggest is that it is something wrong with the code or the wiring.

For more specific advice post your code, read how to do this correctly, and post your schematic, not a Fritzing physical layout diagram.
