555 Intervalometer camera connectionThis is my entry for the 555 Contest recently started by Jeri Ellsworth and Chris Gammell. It is a camera timer (aka. intervalometer) for taking time lapse videos with my DSLR. It is a very simple circuit designed around a 555 timer IC. It has indicator LEDs, a relay to control the camera, and a potentiometer which allows me to set the photo interval between 15 seconds down to around 1 second.

Arduino servoControlling a servo motor with an Arduino or other type of microcontroller is probably the easiest way to get started in robotics, motion art, or any other reason you may have to make your electronic project interact with the real world. Servos are very simple to interact with and in this post I’ll show you how to connect one to an Arduino.

Controlling a Stepper Motor with an Arduino

arduino316As one one of my first projects with my new Arduino I thought I would try to hook up a stepper motor. I had a few laying around from old computer hardware I had taken apart and now I finally have the resources to hook them up.
