My attention is drawn towards the noise behind me...
I cannot believe it.
There it is.
The Arduino is taking a SELFIE!!
How did this happen?
Well actually, it is not that difficult for an Arduino.
I found out that my Canon Powershot SX50 HS camera has a port on the side for a remote switch. In the "Optional Accessories" section of the camera brochure, it identifies the remote switch model as RS-60E3. I then looked up the model number on this website to find out the size of the jack (3 core, 2.5mm), and the pinout (Ground, focus and shutter) required to emulate the remote switch. Once I had this information, I was able to solder some really long wires to the jack and connect up the circuit (as described below).
And before I knew it, the Arduino was taking Selfies !!!

Created: 14th Sept 2014
Arduino IDE: 1.0.5
Description: Arduino takes selfie every 30 seconds
Connect 5V on Arduino to VCC on Relay Module
Connect GND on Arduino to GND on Relay Module */
#define CH1 8 // Connect Digital Pin 8 on Arduino to CH1 on Relay Module
#define CH3 7 // Connect Digital Pin 7 on Arduino to CH3 on Relay Module
//Setup all the Arduino Pins
//Turn OFF any power to the Relay channels
delay(2000); //Wait 2 seconds before starting sequence
digitalWrite(CH1, HIGH); //Focus camera by switching Relay 1
digitalWrite(CH1, LOW); //Stop focus
digitalWrite(CH3, HIGH); //Press shutter button for 0.5 seconds
digitalWrite(CH3,LOW); //Release shutter button
delay(30000); //Wait 30 seconds before next selfie
By connecting up the camera to an Arduino, the camera just got smarter!!
The Arduino connects to 2 different channels on the relay board in order to control the focus and the shutter of the camera. The relays are used to isolate the camera circuit from that of the Arduino. I have also included a couple of diodes and resistors in the circuit as an extra precaution, however they may not be needed.
