I’m wondering if I could get some help. I‘m trying to build a Death Star Christmas Tree Topper and I’m kind of stuck. I came across this Instructables project http://www.instructables.com/id/Death-Star-Christmas-Tree-Topper/ and thought it would be a fun project to do. I got the circuit made and most of the programing done but it didn’t work. I have made some changes to both, but still no luck. I’m wondering if someone might be able to help me finish it off. I’ll admit my programing skills aren’t very good. I put a couple images and the schematic up here and i attached the Arduino code as well.

Any Help with this would be greatly appreciated.

Thank you

Matthew,

If you are planning to use 8 LEDs for the circle, you can't use the sound wave shield as some of the pins are conflicting. You'll have to use an extra Arduino for the sound wave shield. Just let me know and I'll fix it up for you.

I didn't know that. Am i able to double up and run 2 LEDs parallel with each other so i only need to use 4 pins?

Matthew,

You are right. 4 LED pins would work. What is the LED you are using? Instead of parallel, it's better to use 2 LEDs in series. 2 in parallel might draw more current than the pin could provide.

Just some basic Clear green LEDS i got off ebay http://www.ebay.com/itm/100pcs-5mm-Red-Green-Blue-Yellow-White-Ultra-Bright-LED-Light-Bulb-Lamp-20000mcd-/181436212943?hash=item2a3e70e6cf:g:KhYAAOSwWnFWAC15

I can make some adjustments to run them in series off 4 pins. Any chance you might be able to look at the code for me?

Mathew,

Please try the attached file. You can actually use the analog pins for to hook up the 4 other LEDs. See Pin assignments in the code for details. Let me know if it still doesn't work.

Yeah still nothing. Im not sure what it is. I'm not sure if this will help but the Message it gives me when i flash it is

Matthew,

I don't have time this weekend, but next week, I'll mock up a bunch of LEDs and test it.

Thank you. Yeah I wish i new more about this stuff. Hardware im not to bad with but programing isn't my strong point.

Matthew,

I don't have the sound wave shield so I can't check that. But I've verified the LEDs part is working.

Thanks for checking. Im not sure it might be a problem on my end then. I might have to rethink the design or something.

Matthew,

I could help you in person this weekend. Are you going to the iot hackathon?

That would be great, but unfortunately i'm not able to make it. I have to work this weekend. Would you be avaliable another time maybe?

Also just a thought I wonder if it would be easier to use a different MP3 Module instead of the Wave Shield. I have a few others laying around from when i was working on a Arduino Star Wars Blaster project.

Im Free Monday until 3pm and pretty much all day Wednesday or Thursday. Would any of those days work for you?

Sounds good message me on FB and we can go from there if that works with you. https://www.facebook.com/mattnelson521

Also just wondering what Arduino board you're using?
