Arduino (I use freetronics leostick)
a remote plug for your camera
a 4x AA battery pack
3 position switch for version 2
Step 1: Connect the battery and relay
Now connect the coil pins of the relay to the GND and digital 6 pins on the arduino.
Connect the plug for the camera to the relay as shown in the diagram. Make it so without power to the relay, the remote circuit is broken.
Step 2: Upload the code!
change the frame interval on the first line for different settings.
int frameInterval = 3; // Delay between pictures (in seconds)
int shutterPin = 6; // Reed relay on digital pin 6
int ledPin = 13; // LED connected to digital pin 13
pinMode(shutterPin, OUTPUT); // Set the shutter pin as an output
pinMode(ledPin, OUTPUT); // Set the LED pin as an output
digitalWrite(ledPin, HIGH); // Turn on activity LED
digitalWrite(shutterPin, HIGH); // Turn on shutter relay
delay(500); // Hold the button for 1/2 second
digitalWrite(ledPin, LOW); // Turn off activity LED
digitalWrite(shutterPin, LOW); // Turn off shutter relay
delay(1000 * frameInterval); // Wait the required interval before repeating
Now it should trigger the relay and camera every 3 seconds. The relay should be on for half a second and turn off, wait three seconds and turn on, it will do this until the battery runs out.
I will post a sample video on my youtube channel and my website
