Introduction: Spread

Picture of Spread
spread is 2nd work of "unsettled" project. In this work, a camera is controlled by the Geiger counter, and the camera releases the shutter whenever the Geiger counter detects radiation. Thus, these photographs are taken not by a person's will but by an environmental factor. We can notice the subtle difference of these photographs, each of that were taken in different places and radiation levels.

Step 1:


1) Camera: Canon, Nikon, Olympus, Pentax, Sony or Minolta with IR sensor (from
2) Arduino Uno, Nano or else
3) a Geigercounter (I'm always using SEN10742 from Sparkfun)
5) battery packs (if you want to use one outside)

Step 2: How

Picture of How

What you should do to make <spread> is only two thing! Connect a IR LED, an Arduino and a Geigercounter together and let the IR LED blink to release the shutter of a camera. (just like a pic below)

Step 3: Codes

Picture of Codes

/* Using a library from */
#include "multiCameraIrControl.h"

const int GM = 6; //connect Pin 6 to a Geigercounter's OUT Pin
int geigercount = 1;
int null;

/* if you use Nikon camera */
Nikon D5000(9); //connect an IRED to Pin 9 to control camera through an IRED

void setup(){
  pinMode(GM, INPUT);

void loop(){
  /* everytime a Geigercounter detects radiation */
  if(digitalRead(GM) == null){
