Here is the diagram and calculations for my circuits. Was still confused about exactly how much resistance to use for what.
I’ve been looking forward to using Arduino in projects for a long time, so it was nice to get started last class. I like the hands-on nature of physical computing and the fact that you can see the immediate result of your work, which is a change from Processing.
I’m still new to making circuits and using electricity, so it would be nice to understand those concepts a bit more. Why do we use certain resistors for certain components? How should this be calculated? Do you need to refer to the specs of all components?
