Time-Lapse Photography

Step 9 Programming

Now is time to program the Arduino and test your setup.

Follows is my code:

/* Time-Lapse Camera Controller

• ------------------

*

• Hits a camera shutter at a set interval
• for time-lapse photography. The rate of the
• delay can be manipulated for unique effects.

*/

int camPin = 7; // sets the camera shutter pin
int stupidvar = 30000; // sets the delay between pictures

void setup()
{
pinMode(camPin, OUTPUT); // defines pin as an output
}

void loop()
{
digitalWrite(camPin, HIGH); // presses the button
delay(5000); // waits
digitalWrite(camPin, LOW); // release the button
delay(stupidvar); // delay between pictures

// stupidvar = stupidvar + 1000 // increments delay by one second for unique effect.

}

Wouldn't the relay just spit dangerous voltage back into the arduino's pins when it releases the switch? I think you might want to put a diode between the relay's pin or just use a transistor with it.

So how's it work? Turn the Arduino on, Turn the camera on and it just starts snapping pictures like mad?

Pretty much, the Arduino just keeps running at whatever interval you set. Simply connect them together and turn them both on.
