Description
Build a color sorter to sort LEGO bricks or a line follower that will detect different color lines and surface colors. The HiTechnic Color Sensor is “tuned” to standard LEGO colors. When positioned over a surface, the Color Sensor will return a numeric value identifying the target color. The new Version 2 Color Sensor has enhanced performance including better color recognition and longer detection range.
The new and totally redesigned HiTechnic Color Sensor Version 2 (V2) operates by using a single white LED (light emitting diode) to illuminate the target and analyses the color components of the light reflected by the target’s surface and calculates a Color Number that is returned to the NXT program.
