LED Sand Toy. Add extra images. See https://github.com/porrey/ledmatrixide for more details.
Hi, thanks for posting the link for creating additional programs for this, looking forward to the next step. I have built this and am SO close to getting it to work but I think I have something messed up with the accelerometer. I get the different demo programs to work and they toggle / reset with the buttons, but the "sand" is not responding to position. Did you have any problems with that by any chance? I'm so new to this I'm not really sure where to start now. I went through the code and tried to debug a bit and it looks like there isn't an error reading the values xx, yy, zz from the accelerometer.
I didn't have the issue. I recommend connecting an HDMI monitor to the Pi output and then use a Print statement on the XYZ values just to see if your getting any reading. If you do not get a reading check the wiring until you get values.
