i can switch the camera on and off, and i can take pictures or movies. all timed by an arduino.

a 2nd version with an attiny45 is planned now.

with an 3.7V LiIo battery and a weatherproof, magnet mountable box it will be a nice cheap time lapse box in urban space.

/////////////////////////////////////////////////////////////

void setup() {
Serial.begin(9600);
pinMode(13, INPUT); // pic/movie button
pinMode(12, INPUT); // on/off button
}

void loop() {
// switch camera on
Serial.println("cam on");
digitalWrite(12, HIGH);
delay(1000);
digitalWrite(12, LOW);

delay(500);

// take picture
Serial.println("take picture");
pinMode(13, OUTPUT);
digitalWrite(13, LOW);
delay(250);
digitalWrite(13, HIGH);
pinMode(13, INPUT);

delay(5000); // wait some seconds until picture is saved

// switch camera off
Serial.println("cam off");
digitalWrite(12, HIGH);
delay(5000);
digitalWrite(12, LOW);

delay(60000); // wait a minute
}

#### UPDATE ####
3.7v is too low to switch the cam on and off.
its enough to power the cam and take pictures, but switching it on and off does not work with 3.7v.
so i switched to 4x AAA akkus. thats 4.8v and does the job nicely.
ill check how long i can pictures with them at the momet.
