QTR-8RC Reflectance Sensor Array | This sensor module has 8 IR LED/phototransistor pairs mounted on a 0.375" pitch, making it a great detector for a line-following robot. Pairs of LEDs are arranged in series to halve current consumption, and a MOSFET allows the LEDs to be turned off for additional sensing or power-savings options. Each sensor provides a separate digital I/... | $16.88 | |

Snap-Action Switch with 16.7mm Lever: 3-Pin, SPDT, 5A | This single-pole, double-throw (SPDT) switch can be used as a general-purpose micro switch or tactile bump sensor for your robot. The switch body dimension is 20.0 x 6.4 x 10.2 mm, and the lever arm is 16.7 mm long.This single-pole, double-throw (SPDT) switch can be used as a general-purpose micro switch or tactile... | $0.85 | |
 |
Pololu 42x19mm Wheel and Encoder Set | This set includes a pair of 42×19mm wheels, a pair of extended brackets, and two matching encoders. Just pick a pair of micro metal gearmotors to complete your feedback-enabled drive system.This set is intended for those looking to create a differential-drive robot with dual quadrature encoders. Just add two micro metal gearmotors of your... | $41.53 | |
 |
Pololu IR Beacon Transceiver Pair | The Pololu IR beacon is a compact board that is used in pairs to allow robots to locate each other. Each board has infrared emitters that shine in all directions and four IR receivers for detecting the other beacon. The IR beacons have a range of about fifteen feet indoors. This item is for a pair of beacons in one package. | $54.45 | |
 |
Card Reader - SD/microSD/M2/M5 Duo | Card Reader - SD/microSD/M2/M5 Duo sku: COM-10993 Digital storage cards are like the floppy disks of our time. They're used to share data between devices like cell phones, cameras, computers and even Arduinos and the like. No matter whether it's carrying pictures from your High Altitude Balloon project, accelerometer data from you... | $6.00 | |
 |
GWS S689-2BB/MG/JR Giant Servo | For projects that require brute strength, look no further than the S689-2BB/MG. This giant-scale servo from GWS delivers extremely high torque, and it doesn’t sacrifice speed to do it. The output shaft is supported by two ball bearings, and the gears are metal for increased durability. Servo horns and associated hardware are included.Key... | $67.00 | |
 |
Elenco AK-510 Motion Detector Kit | Learn about electronic motion detectors with this deluxe kit that includes a high-quality enclosure with a mounting bracket. The motion detector makes a loud, doorbell-like “ding-dong” sound when it detects motion. The kit is based on a pyroelectric infrared (PIR) sensor, which is a unique sensor that you can use to give your project... | $27.65 | |
 |
Encoder for Pololu Wheel 42x19mm | This quadrature encoder works with our micro metal gearmotors, 42×19mm wheel, and extended bracket to measure the rotation speed and direction of the wheel. With twelve teeth on the wheel, the system provides a resolution of 48 counts per revolution, which corresponds to a linear resolution of just under 3 mm or 1/8".Overview | $16.88 | |
 |
Pololu IR Beacon Development Board | The IR beacon development board is just an assembled IR Beacon PCB with no IR sensors or firmware. This item is intended for advanced users who want to customize their IR beacon functionality by writing their own firmware. No documentation is shipped with this IR Beacon Development kit. | $16.88 | |
