After working independently to make lights blink with our arduino boards, we gathered into groups, in true Smartsurfaces fashion, to expand on our newly developed skills. This week we combined the LDR light depending sensors with servo motors to create a contraption that follows or tracks light on two axes.
Objectives:
Your team's task is to design, build, program and test a device that tracks a light source (handheld flashlight). This system should operate on dual axes and be active. Ideally it should be capable of:
- Tracking the light horizontally
- Tracking the light vertically
- Indication when it is in alignment with the light.

What you may not be able to see in the video are the lights that turn on when the light is "directly" in the center. I say "directly" only because we rigged up two LDRs so we could incorporate two colored LEDs, if for no other reason than spectacle. When the light (flashlight) is directly on one of the two LDRs (located in the center) a red or blue light shines through the smiley face cut out of the base.
The code for this project can be found on team member Michael Mathieu's blog.
