Annoy Me!

I snagged a Ethernet shield for $4.00 and wanted to use it right away. I found some tutorials online to control various devices and decided, just for fun, to make a project that will annoy the heck out of me. Head over to http://projects.mytestbox.org:8002 and see that you can control very bright LEDs.

Unfortunately, the webcam isn’t real time. It updates the picture every two seconds. Also the WS2811 seems to be a bit glitchy, so sometimes there will be incorrect LED colors displayed.

Have fun!

Binary clock using Arduino, DS3231 real time clock, and WS2811 Addressable LEDs

You may have remembered I started working on a binary clock project with the Arduino. There are two things I didn’t like about that project. First, the clock didn’t keep time. It ran about 37 seconds fast. Second, it required the use of almost all pins on the Arduino. I started working on a new binary clock project with the requirements that it kept accurate time, it didn’t use as many pins, and I could set the time. I sacrificed the addressable LEDs I had used for my Christmas Tree lights and began to work on the new binary clock.
