Phototropic Robot Science Fair Project

For this year's science fair project, I added four light sensors to an iRobot Create and tested them to see which number of sensors would help the robot find a light source most efficiently. It turned out that the number of sensors and the time taken to find the light source are negatively correlated. In conclusion, three sensors (front, left, and right) make a model that maximizes efficiency and use of peripheral ports.
