[Pcomp] Using Analog and Digital input/output – Op Turntable

I do not know why but I am into seeing and experiencing optical illusions, Op art or kinetic art.  When I went to paris, I went the Dynamo exhibition(A CENTURY OF LIGHT AND MOTION IN ART, 1913-2013) that mostly focused on Optical illusion. I really loved it until now!

I wanted to mimic one of the art pieces, using two different patterns to make like moire effect.  And I tried to make a turntable control speed and on-off. And I also get inspired the OPARTICA site, then I drew them to cut by laser printer with black acrylic.



  • a geared motor (already slow motor 1-5V~3V )
  • toggle switch
  • potentiometer
  • Arduino
  • transistor
  • 2 power diodes
  • 2 x 1.5v AA batteries

I followed this resource in ITP Physical computing site. (Lab: Using a Transistor to Control High Current Loads with an Arduino) and I added one toggle switch.





And there was a connection problem, I thought my breadboard is old and too loose to hold the jumper cables. I changed to new breadboard but it still happened. Finally, I realized one red jumper cable is disconnected!! It was a really simple problem, but I spent a long time to figure it out. (I won’t believe jumper cables!)

And even though it was a very first project for me, I would like to explore more about kinetic and op art. (different speed of two disks, up and down, more than 2 disks and so on)
