I gave up on trying to drive the A6280 directly with the Arduino. macetech.com already did what I wanted but couldn’t do myself. They used the A6281 (which doesn’t come in a DIP package- only an SMC) on a nice little breakout board with a RGB LED. Yea!
One of my bestest oldest friends is an electrical engineer/genius. So I asked him- how do I drive 3 LEDs from the least number of Arduino ports?
This thing will drive LOTS of these little LED drivers from the SPI serial bus.
I’m so giddy! Digi-Key order is in! Spec sheet after the jump.
The PowerSwitch Tail II is a great and VERY simple way to have the Arduino control AC powered devices. I’ve used these in my LCC project. The Arduino can control these directly from a digital IO port, BUT you’re better off using a transistor to drive them, just in case…
You can get them at SparkFun.
This is a really geeky article about LEDs that produce more light than the electricity put into them. Or some such thing. Give it a read. I wonder how this could be helpful to makers?
