Looking for a method of creating a count-down timer to activate camera functions used for his interesting video blogs, Dave Jones harnesses a cheap universal remote-control and modifies it to allow for control by our Freetronics Eleven Arduino Uno-compatible board. This is a cheaper and more interesting option than modifying a genuine remote for the camera, as the universal replacement can be trained with the required IR signals. Dave then deconstructs the remote and explains how the keypad matrix circuit works, which then leads to controlling it via the Eleven. This allows for all sorts of customised orders of command for the camer and more.
If you're new to Arduino and want to join the fun, the first step is a solid board for your projects - our Freetronics Eleven - the Arduino-Uno compatible with low-profile USB socket, onboard prototyping space and easy to view LEDs:
