Hey there, sorry to hear that you're having trouble with the programming of your blinky POV. Have you checked out our cool new animated guide to programming
If you re-do the programming at 40ms, 80ms, or 120ms, does it have the exact same
end behavior each time? For example, with 120ms, is the second LED always
the only one lit, or does it sometimes have no LEDs lit at the end?
Do you have a smartphone like an iphone or ipad or android device you could use to test it out?
If you can take some high-resolution digital photos of both sides of your circuit board, and close-ups of the sensors if you can, that'd be great. Feel free to send us a message via the contact form
if you still can't get it to work.
