ステップ 5: Activate the Camera Shutter with a Microcontroller

The best way to automatically control a camera is with a microcontroller such as an Arduino. To connect the microcontroller to your camera, you will also need are a small diode and a jumper wire. 

Insert the cathode of the diode (the side with the stripe) into one of the digital pins of the microcontroller. Then insert the jumper wire into one of the GND pins on the microcontroller. Now you need to connect these to the shutter switch cable. The jumper wire should connect to the ground of the camera. The diode should connect to the shutter function on the camera. 

When the microcontroller sends a LOW signal to the digital pin, the camera shutter should activate. But when a HIGH signal is sent to the digital pin, the diode becomes reverse biased and prevents the electricity from flowing into the camera. This protects the circuitry of the camera from being potentially damaged. 

Using the microcontroler, you can easily incorporate your camera into any kind of automated system. 
<p>I made something similar using atmega328p CPU (Arduino)</p><p><a href="http://www.instructables.com/id/APCC-Advanced-Photo-Camera-Control/" rel="nofollow">http://www.instructables.com/id/APCC-Advanced-Photo-Camera-Control/</a></p>
is there a way i can do it with it detecting sound or vibration and then have a dalay you can change
Yes. If you are using an Arduino, you can use any number of sensors or even multiple kinds of sensors at the same time.
canon 550 and 650 becomes unstable with diode.. replacing diode with optocouplers (moc3020) will do the job..
hi, i followed your plan here, and my output is holding &quot;short circuit&quot; for a long time at every interval and sometimes will trigger twice. any ideas?
Your camera probably keeps taking pictures as long as the shutter switch is pressed. You could use a smaller resistor to shorten the interval time.
nice but one question <br>under step 6 in your 5th picture it looks like pin 3 isn't connected, but it is in picture 3. <br>which is correct? i've build it like picture 3 but it doesn't work
In the 5th picture pin 3 is connected to the left end of the yellow jumper wire. This connects it to the middle pin of the potentiometer. It is wired up as indicated in the schematic except that I used a variable resistor instead of a fixed resistor.
mine looks similar. if i start it takes a little time and then it makes pictures every second. can't add an image here

Awesome!! .... :D
Very nice and comprehensive tutorial. Thanks for posting this.
