Experiment: 20100806
I have successfully constructed my first “hey, I wonder if I can just make that” Arduino project using a for loop to light LEDs in sequence, then turning them off in 5 minute intervals over a 60 minute period. I’m inordinately proud of myself, despite the simplicity of the project and the fact that I had to toss out the buzzer feature I had first envisioned. (I’m guessing I got the wrong kind of buzzer at Radio Shack as it sounded like a congested squirrel.) My gaming group and I will be using it as the official countdown timer for our home-grown RPG themed cooking show tomorrow.
Shopping List:
12 220Ω Resistors
3 Red LED - 5mm
3 Green LED - 5mm
6 Yellow LED - 5mm
1 Arduino
1 Half-Breadboard

Awesome! The road to learning the Arduino is a fun one. Maybe one day you can revisit this same project and use 4 IO pins instead 12 using Charlieplexing!
