Arduino: Modern Bedside Lamp

I created my work based on a traditional Japanese room light, “andon”. Andon became very popular in the Edo period,1603 to 1868 in Japan. Traditionally, an andon is a wooden structured light that has a candle or a dish of liquid fuel in it. I used white LEDs as light for this project.

The light is usually diffused and softened by paper, called “washi” that is attached to the structure. Washi is a special type of Japanese paper that has high reflectance and a unique texture that is made by thick fibers in the paper. I simply used tracing paper to imitate the diffuser, and it is much smoother than a traditional one. In addition, I placed a laser-cut wood piece with a geometric pattern on top of the light. I made a pattern to look modern. The pattern will become visible in the dark. The flicker of the andon flame is a big part of the visual experience. It gives very relaxing and almost therapeutic feeling. I created the flicker digitally with Arduino. I used to PWM (pulse-width modulation) to control the LEDs’ brightness and made them beat. The slow and smooth beating seems to match to materials, wood and tracing paper. Overall, the lamp is very relaxing and soothing.

void setup(){
pinMode(10,OUTPUT); //Set pin 10 as output
}

void loop(){
int i;
  for (i=30;i<=255;i++){ //initialization; condition; increment or decrement
    analogWrite(10,i);
    delay(15); //set fading speed as 15(ms)
  }

  for (i=255;i<=30;i--){
    analogWrite(10,i);
    delay(15);
  }

}
