I actually think the scroll up doesn't work. I set stream to 5 seconds for both scroll up and scroll down. Here is a test with the preview function in stream:https://youtu.be/DHmEznD5iBUAnd a test with it saved and disconnected:https://youtu.be/Fz4_BedHTvM
JakeSoft, I used the updated file as instructed, and I met with success for the most part. It took a bit of fiddling with my wiring connections to get it to work. At first, the power up sound would play, the pixels would scroll as intended, but before the pixels finished scrolling, the sound would cut out like it was doing before (at least this time the pixels were scrolling). I tried changing to one of the older batteries, and the scrolling and sound barely did anything. So I know for sure those batteries are insufficient. I wired back up the newer samsung (20 Amp continuous draw) battery with better wire contact, and met with success! The sound played normally, and the scrolling worked. The aux button is a little finicky, but I think I just need to solder up some stable connections. I'll report back should I encounter any issues. In the mean time, thanks so much for the incredible support!(jbkuma- I did have a 220 Ohm resistor between the data line and D13, I assume that's what you were talking about with your first point? Regardless, thanks for your input!)
This is my first build. I've read this thread from front to back learning from all the experiences that all of you have had. I've encountered a few issues myself that I haven't seen posted here.HW:Arduino NanoMPU6050DFPlayerI followed the pixel blade diagram (- wired to GND instead of RST) I have to use 7.4v wired to VIN with 5v to drive the dfplayer and pixel strip (220 ohm res on data pin)it works fine, and I'll use this one in a double bladed saber.one 3.7v 18650 doesn't power on my build. I'd like to have a smaller hardware setup. my next build will use the Arduino Beetle, but I need to learn what to do in order to drive the saber with a single cell 3.7v batt. the only difference in my build from the diagram is moving (-) from RST to GND.has anyone else had this issue? fully charged cells are reading at 4.2vhttps://www.youtube.com/watch?v=Nm3xZX-npHoAlso, can anyone point me to the place in the code that would allow me to adjust the ignite speed?
