Wow Tom -- thanks for being amazingly helpful and detailed with your explanation.  That was exactly what I was hoping for. I read and the re-read what you wrote line by line, several times until I had an intuitive feel for what's happening.

Guess that leads me to wondering if anyone has suggestions for future kits/projects that combine this kind of theory and explanation with the kit/project itself?

Best - Bryan

Hi, 

I'm new to hardware and I've been working on SparkFun's getting started projects (I'm on project 3 "transitors & motors") and I've uploaded a detailed JPG "step-labeled" photo with my wires, resistors, transitors, diodes, etc all connected.

So ... plugging some wires into a breadboard and copying directions & code and having something "work" is great.  But I (like some other newbies -- from what I've read on the NET) are a bit lost on how the current flows through the whole circuit and the why resistors and diodes and components are in particular places in the chain (and physically on the board) and what they're doing.  Initial questions that come to mind are "could i have moved this wire to a different column, row, etc?"  "In what component order does the current flow?"

Lastly, being that I've uploaded a pretty detailed JPG of my components/wires connected --  could some nice souls who understand this shed some light on anything you deem worthy of explaining related to what's happening in the diagram -- especially any pointers related to the event chain.

- Thanks, Bryan
