we put in a handy 9-segment bar-graph for indicators

which gives you a lot of flexibility in how you can put them together and what you can mount to them (see the bumper cage kit dimension diagram (152k pdf) for more information)

QTR-MD-08A Reflectance Sensor Array: 8-Channel, 8mm Pitch, Analog Output Shipping:1 day The OpenPIR has a multitudepitch sensors size (mm) output max current optimal range LEDs board 8mm8 61. 0 20. 0 analogous 30 mA 125 mA 5 mm This 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. In general, the closer the object, the higher the contrast between light and dark readings, but high
