Cute Little Valentine's Day Gift 🌞🌞

PCBway: only $5 for 10 pcbs from www.pcbway.com...
It’s almost Valentine’s Day. This year, instead of giving her a rose bouquet, I wanted to express my love by gifting her an electronic breathing heart. This is yet another "cheap DIY kit" intended for educational purpose. There are a few variations of the breathing LED projects with similar setup, however the one with blue LEDs attracted me a lot.

great idea, simple design and parts. could you kindly send us the pcb file so we could just print it by ourselves. I would be grateful if you could

I bought the pcb from Aliexpress..
However, I do have a couple of videos on the same using lm358 ic
Please checkout my tutorial 24. I have a Gerber that u can use for the same. Just remember different colors have different forward voltage, so keep that in mind.
