If you have to chance to test it, give it a try. One of the most useful uses of arduino turning a common camera in a cinema tool.

I call it Intervaluino, and it does exactly what I want him to do: Tell my Canon EOS 400D to take pictures at regular intervals. Wanna build one yourself? Please follow me.

you’ll  need:

1 Arduino (I used the Diecimila model) –

3x 100 ohm resistors

1x 10k ohm resistor

2 x 5V reed relays (NO = normally open)

1 x push button of your choosing

1 x 2.5mm male stereo jack

1 x 80 x 50 mm strip board
(alternatively: bread board or Arduino protoshield)

Assorted wires

Arduino USB cable

Arduino AC adapter OR Arduino 9V battery pack

Basic electronic tools to cut and de-isolate wires and to solder components (if you use a strip board), maybe a multimeter to test connections

A nice box

20 cm of thin steel cable (used as a loop to attach the Intervaluino to the tripod)
