Hey team! I just received my toolkit with the soldering iron and other parts, so was excited to get to work this weekend.
While I was able to get the one panel LED to work in step 006 with the original test code, the cube stopped working when I expanded it to 2 panels (by the instructions, I didn’t know if I was supposed to use strandtest-1.ino as well for the two panel test, and if so, what “The following code is meant to test the IMU. If you do not wish to use the IMU, this code will not work. Instead, modify the strandtest code to test 32 LEDs, rather than just 16” meant. Modify to 32? Does that mean for the final product I need to modify it to 96 (16 x 6 sides?)
When the two panel test didn’t work, I just figured I would have to assemble the full cube and there might be more code later on for me to use. That didn’t end up working
I uploaded strandtest-1.ino as is onto the Uno board connected to the cube, and unfortunately the lights didn’t turn on. Not only that, but I noticed the wires connected to the board started to heat up a great deal, eventually with a little smoke emitting from the bunch. Anyone else had this problem?
A few additional notes
- I made sure the cable pins were placed into ground, #6, and 5v, and ground
- This is my first time soldering, but I checked to see if I had any touching pieces of soldering material and this didn’t seem the case. I even went back and cleaned up any soldering jobs that might be touching.
- I did burn the LED board a bit when I was soldering in the pins – you can see this in the images.
- I have an extra Uno board, so I tried the cube with that one. Same thing happened - the wires started to smoke.
I’ve included some images for reference. Any thoughts on how to best troubleshoot this? Like I said, I had the first panel working but it seemed to go down hill from there. Now that the cube is all put together, getting back to just one LED panel is a bit of a headache so was trying not to take the full cube apart if possible.
