Tinkering with individually addressable LEDs…

April 19, 2015 | Arduino, LED, Microcontrollers, My Projects | By: Mark VandeWettering

While digging around looking for an LCD module I thought I had stashed somewhere, I encountered a bag with some of 8mm individually addressable RGB LEDs that I had never done anything with. For fun, I thought I’d wire a few of them up on my breadboard and see if I could get them to […]

More ESP8266 Experimentation: Giving it the Boot…

April 4, 2015 | Arduino, Hacking, LED, My Projects | By: Mark VandeWettering

Got a chance to play around a bit more with the ESP8266 tonight. I dug out a nice little dual output power supply board that I had got from tautic.com with the hope that it would eliminate some of the erratic behavior that I had observed before. Sadly, that didn’t seem to solve my problem. […]

Making a simple RC switch…

June 14, 2014 | electronics, LED, My Projects | By: Mark VandeWettering

Over the last couple of years, I’ve spent a little bit of time making fixed wing aircraft from Dollar Tree foam. The results have been interesting and fun, but I’ve found that the need to find relatively large areas to fly means that it’s harder to go fly than I would like. On the other […]

Project Completed: My $.99 Christmas LED hat, with ATtiny13 controller

December 18, 2011 | Arduino, diy, electronics, LED | By: Mark VandeWettering

Well, it’s done! Here’s my ATtiny13 controlled Christmas LED hat. It consists of an 8 pin, ATtiny13 microcontroller, a pair of 2N3904 transistors and some 1K resistors, a 7805 voltage regulator with two filter caps, and a switch, all mounted on a Radio Shack perfboard inside an Altoids tin. I’m rather pleased with the way […]

Carmen makes an Arduino Stoplight

December 12, 2011 | Arduino, electronics, LED | By: Mark VandeWettering

Today, Carmen decided that she wanted to give Arduino programming a try. She’s an experienced programmer, but had never tried any of this small embedded stuff, and knows relatively little about electronics, but with a little direction from me, she got the Arduino development environment installed, and we did a bit of playing around. I […]
