  • LED Heart Photo Frame - Make a Perfect Valentine's or Birthday Present

    ...which is awesome, by the way ! This is what the TLC's are for, imho. I have a question to you, gkelly2 (hope you're reading this). First, what is "Charliepixeling"? I can't find anything about it on the internet. Is it a form of Charlieplexing?Second, the author used 32 LED's in a heart shape and used 4 Pins of a uC. To charlieplex 32 LED's you would need at least 7 Pins. Wouldn't that be worse? Some answers would be awesome ! :)
