The Moire Effect

With use of a motor and images that have a subtle sense of alignment, I tried to create a lamp that has a Moire effect as it rotates. The motion effect would change depending on the speed. I had also designed the patterns to recreate the effect.


  • Arduino Uno
  • DC Motor
  • Design of static Moire patterns
  • Transistor TIP120
  • Semiconductor 1N4004
  • Jumper wires
  • Potentiometer
  • 1k Ohm Resistor

int potPin = A0;   // 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
