How can I change the color of a RGB LED with the push of a button (i.e., push once for red, again for green, etc.).
I have to laugh when I see the prices of flashlights that have multiple LED colors. $50 for a headlamp with 6 RGB LEDs? Really? I have seen "Buy It Now"s on eBay that have 50 pcs of RGB LEDs for ~$17. Besides, the fun is in building one myself.
