Spooky Arduinon Projects #3 – DIY Ambient orb
Todbot writes – “The notes for the third class are up on the Spooky Arduino class page. Also are links to many of the Arduino code sketches used in the class. Here’s a 10-minute project that’s a glowing orb thing similar to the Ambient Orb (but much larger!) using the techniques from this week’s class.” […]
