When filming your projects—or day-to-day life—static shots can be fun, but having a moving perspective often looks even better. The challenge is keeping the camera pointed at your subject, which maker Saral Tayal addresses with his automated slider.
This Arduino Uno-controlled slider is powered by a pair of brushed DC motors with encoders attached for feedback. One pulls the camera along a pair of rails on a set of linear bearings, while the other adjusts the camera’s horizontal angle using trigonometry to keep a particular object in-frame.
Code and print files are available in Tayal’s write-up, and some beautiful resulting shots with an explanation of the project can be seen in the video below.
