New Video Design Idea, click for a cause

If I may step into Charles Small’s space for a moment, I’d like to give Design Ideas fans a heads-up. Actually, three.

1) Today marks the debut of a new Video Design Idea. Presented by frequent contributor Dhananjay Gadre, the video details the use of "Charlieplexing" to drive 20 LEDs from six available I/O pins on an 8-pin microncontroller. Check it out.

2) More importantly, all your clicks on EDN.com today will do more than expose you to excellent technical content (if we do say so ourselves). For every page served on the site today, we’re donating a penny to Alex’s Lemonade Stand. A penny might not sound like a lot, but it adds up, so please click generously.

3) Here’s something you might consider clicking on: Today only, we’re running a survey on EE Career Satisfaction (or lack thereof). Filling out the brief survey gives you a chance to win an Apple iPod Touch.

Thanks.
