Taking timelapses is a fun pastime of many a photographer. While most modern cameras have some features to pull this off, if you want to get really into it, you’ll want an intervalometer to run the show. Chasing just that, [Zach] decided that rather than buying off-the-shelf, a DIY build was in order.
The build relies on an Arduino Nano to run the show, in combination with the popular HC-05 Bluetooth module. The Bluetooth module allows the device to communicate with a smartphone app which [Zach] created using RoboRemo. This is a platform that makes creating custom USB, WiFI and Bluetooth apps easy for beginners. The app sends instructions to the intervalometer regarding the number of photos to take, and the time to wait between each shot. Then, it triggers the time lapse, and the Arduino triggers the camera by shorting the relevant pins on a TRS plug inserted into the camera.
It’s a straightforward build that most hackers could probably complete with parts from the junk box. Plus, building your own offers the possibility of customising it exactly to your needs. Of course, you can eschew modernity and do things mechanically instead. Video after the break.
