Creating an intervalometer is a relatively simple and useful project for any keen photographer. Doing so gives you the ability to create customised time-lapse photography over almost any periods of time, and also have more control over functions that are available with the camera's remote control. By interfacing or learning about the functions of the remote, you can then reproduce your own and this is where the Arduino helps.
Engineer Joe Thompson has demonstrated this process by working from a design that offers infra-red remote control of his Nikon D60, and with some basic circuitry and buttons connected to his Arduino the intervalometer was born. And with it, some amazing results as shown in the playlist below:
If you're looking to learn how to get more from your Arduino or compatible board, you can't go past "Arduino Workshop - A Hands-On Introduction with 65 Projects” by John Boxall.
Arduino Workshop takes the reader from having zero knowledge about the Arduino platform, electronics and programming and leaves them with the know-how and instructions on everything from blinking an LED, to robotics, wireless data, cellular communications, motor control, sensors, Internet connected systems and more.
