I’m pretty new to this arduino stuff and am not so hot on the hardware side of things. I wanted to play around with an 8*8 display controlled with a MAX7219. I followed an instructable here.
Now I’ve done everything in the tutorial, but there are clearly some LEDs permenantly on that shouldn’t be. The pic attached is taken with only vcc and gnd connected.
The video here is what happens when everything is connected.
Any ideas what’s wrong?
