Circuit Options Overview (2012)

For flowers and for cape:

ATtiny vs. Arduino Mini

Left: ATtiny (based on not having a Control module, instead wiring the button input directly to all ATtiny microcontrollers).
Right: Arduino Mini (it looks crazy, but it is actually quite straight fwd, and in my opinion simpler than the previous circuit i proposed.
We can “chalieplex” up to 8 * 7 = 56 lights – n*(n-1).
The sketch is a bit messy, but hopefully it makes a little bit of sense).



ATtiny microcontrollers with more in/out pins >>
– arduino programming supported?
– can microcontroller power more than 4 LEDs at one time anyway?
