My name is Paulo Coelho. I am a creative with a Master degree in HCI from Carnegie Mellon University.

I am from Madeira Island, Portugal and my background is in Computer Science.

This portfolio aims not only to show my skills but to share with the world some knowledge. Because of this, I decided to throw some tutorials in the mix too.

Seeeduino bot

---

Recently I led a studio in TEI’11 and I presented a very small robot I created. It is composed of a Seeeduino film, two pager motors and two light dependent resistors. It was a challenge to create it because it is so small and fragile. It follows light when reflected over the table.

It has two light sensors in the front. It compares the light values and instructs the motors to head to the side where there is the most light. If they are very similar, the robot just moves forward.
