This is a 16 multiplexed sensor bar specially designed for competition line trackers.
 It has 16 QRE1113 sensors multiplexed through a 74hc4067 circuit, this allows the 16 sensors to be read using only 6 pins of the microcontroller (if the LON pin is connected to Vcc permanently, only 5 pins of the microcontroller would be used).
 They can be used with our sensor bar holders.
 It can also be used in conjunction with our 0.5mm FCC / FCC connector to 2.54mm header converter kit w / cable
 We have the example library for Arduino!
