LED Matrix Sand Toy

by Jwylie01 on Mon Jun 25, 2018 8:39 pm

I just finished assembling the LED sand toy and everything works great except for the fact it thinks up is down. All the “sand” rush to the top when the demo starts. Any ideas what could be the issue? The board can only be mounted on the holder one way so don’t think that’s the issue.

I fixed it. Made some changes to the code for all the demos and it works correctly now

This project is really sweet! I had some trouble at first, I'm using a Pi Zero W. When I selected the "solder" option during the install process, I couldn't get the display to work. The instructions for the solder option tell you to solder GPIO4 and GPIO18 pins together on the Bonnet. I don't think Pi Zero's have a GPIO18. The setup worked fine when I selected the "non-solder" option.
