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 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.
