Technologies: Arduino Nano, LEDs, accelerometer

Motion in LEDs is a project about movement visualization. I began by creating a bracelet, which can be worn on the ankle and wrist. It is made from an Arduino Nano, LEDs, and an accelerometer and continuously blinks through a preset pattern. The faster the movement detected, the more quickly the cyclic LED pattern blinks. If the user is moving very fast, and exceeds a specified threshhold, the bracelet will briefly flash blue. The wearer can also switch through the 3 preset patterns when achieving a high enough X-tilt.

I then took long-exposure photographs of people wearing this bracelet. I asked them to walk, dance, jump or do whatever they felt like and then tagged each photo with that action. The resulting photos are then records of their movement in the form of light.
