This overview is a good introduction to the Arduino.
Watch the tutorial and reproduce the experiment that is done in the video.
Your circuit should look similar to this:
This is a schematic for your circuit:
This is the code you should have:
Experiment with your program to determine the minimum delay you can have before the LED no longer appears to be blinking? What “rate” does this correspond to?
After you have the experiment completed, call your instructor over to have it marked.
