QTR-HD-11A Reflectance Sensor Array: 11-Channel, 4mm Pitch, Analog Output LCD Display making the LSb 1 and

making the LSb 1 and setting the slave address to 1101011b by default (this is the same slave address as the L3GD20)

The board also provides a regulated 5V pin which can provide a few milliamps (this is typically insufficient for a whole control circuit but can be useful as a reference or for very low-power microcontrollers)

and these channels can be used with the scripting system to enable creation of self-contained animatronic displays that respond to external stimuli and trigger additional events beyond just moving servos

QTR-HD-11A Reflectance Sensor Array: 11-Channel, 4mm Pitch, Analog Output LCD Display making the LSb 1 andThis array of IR LED phototransistor pairs is great for precisely identifying changes in reflectance (like line detection). It operates from 2. 9 V to 5. 5 V and offers dimmable brightness control independent of the supply voltage and separate controls for the odd and even emitters. In general, the closer the object, the higher the contrast between light and dark readings, but high reflectance objects are generally detectable out to around 40 mm. This
