So I finished my first saber awhile back that used a Nano Biscotte v3 and it worked great. Well I am working on two more sabers and picked up the v4. I put everything together like I normally had but in this case...nothing. no sound, no light, nothing. I am suspicious that I may have hit one of the components on the chip with my iron but I double checked the new schematics for the v4 from plector labs and it is showing that the resistors should be threaded to the negatives of the LED's instead of the positives like they did in the v3. Is this a problem or am I reading this right? I was under the assumbtion the resistors would be wired to the positives of the LED's. Please let me know which is correct and if this would be causing my malfunction or not. Thank you.
