Mandalas, Mathematics, and the Art of Arduino
When: Saturday, October 15 & Sunday, October 16
Where: 1st Floor Lobby – CERAS Building, Stanford
Who: Chad Norman (Pathfinder Learning, Mount Vernon School District, Mount Vernon, WA, USA)
Integrated projects incorporating culture, art, and progressive technology is an engaging way for students to learn and create in the classroom. Participants will engage in a multidimensional project that will explore the mathematics of the Tibetan mandala and the amazing visuals created when mixed with an Arduino controlled strobe light. Participants will use a standard Spirograph set to draw a nested image with various radial symmetries on a circular piece of paper mounted to a blank CD. Next, each group will construct a mounted CD motor circuit with a switch. Participants will then construct a simple Arduino controlled strobe light using basic components found in most makerspaces. The interaction between the spinning mandala and varying strobe rates creates surprising images that lead to rich discussions around math, science, and art. There are entry points for beginners and advanced makers. Concepts explored will include radial symmetry, ratios, electrical engineering, and basic Arduino programming. The lesson is flexible in its appropriate grade level and has intrigued students from first grade to college.
