Color recognition system

A Special Color recognition system identifies the ports of digital, analog, and IIC with the colored labels.


The ELECFREAKS PlanetX 4-Channel Tracking Sensor has integrated 4 groups photocell recevier and the fill light LEDs(We call them all as the Probes). At the mean time, it is able to learn by itselft, which means it could adapt to colors in different gray levels.

Press the learn button to learn the map background and the line following path(the black track ). Follow with the following procedures to complete the learn:

  1. Face the probe to the background part of the maps and press the learn button.
  2. The 4 probes indicators light on in turn and the 2 learn indicators flash alternately.
  3. If the fill light flahes in a high frequency with the colorful light, the line-following probe should be moved horizontally back and forth on the background map and the line-following track.
  4. Keep moving back and forth until the fill light of the line probe stops flashing, and the learning is completed.

Note: The height of the line tracking probe from the ground should be among 8mm and 16mm.

After the learning, the two learn indicators will be off. When the probe detects the track, the corresponding probe indicator light will be on. When the learn fails, the hollow circle and solid circle LEDs flash rapidly at the same time, and the fill light RGB light goes out.
