Due is also rather large and I can't solder deadbug onto SMD ICs. Even if the package are using SOJ pins, the tiny pin can still shift around and even break off. I am using ATTiny84 as it's the smallest DIP package that can handle 10 LEDs in the form of Larson scanner
Guess I'll play with a variable resistor. I am using SMD LEDs and I will be using the code I posted at The quirk of using different CPU and PORT - Microcontrollers - Arduino Forum.
Basically as small as possible Larson scanner to fit in a LEGO model of KITT. I was planning to use some 0805 LEDs as I could fit 10 inside the space with bits of gap in between the LEDs. This is the build I am aiming for:https://www.reddit.com/r/lego/comments/72meai/i_built_umkdirs_kitt_moc_and_i_love_it/
3 stud spacing = 24mm. The 0805 LEDs is something like 1.2mm if stacked veritcally and spaced about 1mm apart should leave me about 1.5mm left on either side. I'd go for 11 or even 12 LEDs but the ATTiny84 I am using is using up 448 bytes of RAM out of max 512 and won't be able to handle any more without finding a 1KB version of the 14 pin chip.
I'd have to experiment to see if white LED behind red transparent piece looks good or if I should go with red LED behind red transparent piece.
