 The infrared LEDs emit light towards the ground, and the phototransistors detect the reflected light. When the sensors pass over a line (typically a dark line on a light surface), the amount of reflected light changes. Dark lines reflect less infrared light compared to light surfaces, allowing the phototransistors to detect the presence of a line.

 ### Color Sensor
 
 The color sensor on the Arduino Alvik robot is used to detect and identify colors on surfaces that the robot encounters. It provides both raw color readouts and labeled color information that can be used for various applications such as line following, object detection, and more. The sensor used is the APDS 9660.

 ### Detecting Obstacles

+These sensors provide detailed readouts from multiple positions around the robot, including **left**, **center-left**, **center, center-right**, **right**, **top**, and **bottom**. Unlike single-point sensors, these distance sensors offer comprehensive zone-based information.

+
+The distance sensor array is divided into five distinct zones: left, center-left, center, center-right, and right. Each zone measures distances and is capable of detecting objects up to three meters away. It's important to note that while the sensors can detect objects at greater distances, the reliability of the readings may decrease.
