Qdeathstar: Also literally typing "how to wire an led to arduino" in google will result in a step by step process.
Unfortunately, many of those tutorials are written by people only marginally less ignorant than the one that's looking for help. They may contain things that are wrong, unnecessary, or suboptimal, but neither the writer and certainly not the searcher would have the proper theoretical know-how to be able to understand the circuit.
Learning how to blink without delay was my first "problem".
I certainly think this is a major stumbling block for many people. Freeing yourself from delay is one of the greatest things you can do to fully utilize the capabilities of the microcontroller. I've been trying to write an essay about the subject, but my writing skills haven't been up to the task.
