Lab 6 - Phenakistoscope

Submitted by fchasen on Tue, 03/12/2013 - 22:34


Created a automatic Phenakistoscope. The precursor to the Zeotrope, a Phenakistoscope is just a disk with holes cut in it. Looking through the slits in the disk, with a mirror in place let you see a animation of the pictures on the disk.

The disk I found online is of a galloping horse, clearly influenced by Muybridge's work in photography.

A potentiometer controls the speed at which the disk spins, while wooden dowel gives it some stability.

Code is from the example.

Components Used

  • Arduino Uno
  • Breadboard
  • 1k Resistor
  • DC Motor
  • TIP120
  • Potentiometer
  • Wooden dowel
  • Paper printed disk, with slits cut out



int potPin = 0;   // select the input pin for the potentiometer
int motorPin = 9; // select the pin for the Motor
int val = 0;      // variable to store the value coming from the sensor
void setup() {
void loop() {
  val = analogRead(potPin);    // read the value from the sensor, between 0 - 1024
  analogWrite(motorPin, val/4); // analogWrite can be between 0-255
