hi thereI'll buy some shift registers in the near future and would like to ask which oneI should buy... I'll certainly go for the 74HC595 but which version. There is onewith DIL-16 and one with SO-16 enclosure. I unfortunatly don't know what thatmeans... can anyone help me?
(oh by the way, is it normal that white LEDs are alot more expensive than allthe other colors?)
ok, and another question... I don't want to spam the board, so I'll ask here:Is there an easy way to calculate the approximate time arduino runs on battery?I'll use around 50 leds. I remember there was some kind of a formula. I shouldbe able to calculate this if I know what kind of battery I'll use and how much theLEDs need, right?
thank you! I might have to rethink my concept then. It's supposed to be some kindof a wrist watch .
I live in switzerland, any good advice for that region?
