Just for the love and light of Science, here it is.
Connect +ive to +ive of sequin LEDs with conductive wire, and -ive with -ive. The two shouldn't overlap, or the battery fumes. And disaster strikes right there.
If you're an amateur like me, its a really fun and flashy project. Take it to the clubs or woods. Your very own Signature Style Fashion.
Enjoy this project?
