How to: LED Hard Drive Clock using Arduino



Ah…the Arduino.  The super powerful, easy to program microcontroller brings us another fantastic DIY project.  We’ve seen a few hard drive LED clocks in the past, but this one looks outstanding and is easier to create.  It uses POV (persistence of vision) to create the illusion of a clock while the drive is spinning.  The code will be released soon and you can also view more details about the project.  You can buy dirt cheap LEDs for your projects in our store.
