this is my first post, so bear with me
. I'm an architecture student and
for some time now, I'm planning a wrist watch that I initially sent into a
I would like to create this watch and develop it further by using the arduino
I have ordered the arduino diecimilia kit and I'm just about to start learning elecronics.
I have had some contact with electronics (e.g. building a diy projector), but apart
from that, I'm quite a newb...
So here I have some questions:
- clock in general: how precise is the arduino board? do I need an extra quartz? And how would
I use it?
- how big is the arduino mini? I've read about width and lenght (3x1 cm), but I've seen nothing
about the height of the board...
- LEDs: I'll need to order a number of LEDs. What will I have to look at while ordering them?
Do they need to be 5V? Or could I also order 3V LEDs? And where can I find information which
LEDs need what kind or resistor?
- and finally: do you know of a super easy explanation of shift registers? I've read the tutorial
on this page, but I frankly don't quite get it. I'll certainly work it out for myself, but it would
be nice if there was an easy explanation of the concept behind it, somewhere...
sorry, I know, these are quite a lot of questions, I'm thanking
you in advance for any help you can give me!
