ok, I've bought the components and everything works as expected. yay!

now on to some questions... I'm going trhough the shift register tutorial and

it's running allright (with 8 leds at the moment). I'm drawing the plans at the

moment for a prototype, next week I can lasercut the enclosure.

until then I have some questions about binary math... I was never good

at it at school, but now I seem to need it. I was just looking at the code

example, where there is the line:

shiftOut(dataPin, clockPin, 255);

which lights all eight LEDs.

Am I right that 255 is all eight binary values (0-7) converted to decimal again?

so it's:

000+001+010+011+100+101+110+111

unfortunately I'm unsure how to add these digits together... I looked

at the wikipedia tutorial, but I'm still unsure... Can anyone help?

thanks for all your help! next week there will be pictures! 8-)

**update:** haha, just found out it's alot easier... 255 is 11111111 so I guess

each bit represents the pin on the shift register. so if I would like to only light up

the first led, it would be 1000000, or 64, correct?
