From the Forums: SpiroGraph 3D Laser Project with Arduino #arduino

User IronJungle shared a SpiroGraph 3D Laser Project in the Adafruit Forums!

I have done several projects, but wanted to play with the Arduino. Instead of just getting an LED to “Hello World”, I decided to lump a few basic, commonly used uC features into one easy project. Results were good. I learned many of the Arduino basics and was left with an interesting project.

Maybe it can help someone else get Arduino motivated.

SpiroGraph 3D Laser Project [with Arduino]

Objective: Reflect a laser beam off mirrors mounted on three fans to display a ‘wild’ 3D spirograph type pattern on any surface. Provide fan speed control (manual or automatic) to adjust the displayed patterns. Full electrical schematic and source code follows….
