Photographer Tim Suess rediscovered his love of electronics and found synergy between photography and electronics with his project. He has used an Arduino board to create a simple intervalometer to use with his Canon EOS 400 camera system. It also works with any Canon camera that has a 2.5mm remote shutter release socket. Using the Intervaluino you can control the shutter release, autofocus and allows an interval between exposures up to 24 days and 20 hours. Furthermore the instructions are quite clear including how to make the remote cable:
Apart from being a useful project it's also a demonstration of how people can use an Arduino to solve a problem. To get started with your version head over to Tim's project page here. And we're on twitter and Google+, so follow us for news and product updates as well.
When making your own intervalometer you can increase exposure delay accuracy or set an alarm for a certain exposure time using a real-time clock module. Here at Freetronics we have the Maxim DS3232 real-time clock IC module:
Apart from keeping accurate time for years due to the temperature-controlled oscillator and having a tiny coin-cell for backup, it is very simple to connect to your Arduino project. A driver library allows your program to easily set or read the time and date. Perfect for clock projects, dataloggers or anything that needs to know the date and time. Furthermore it contains a digital thermometer and 236 bytes of non-volatile memory to store user settings and other data. For more information, check out the module page here.
