Single-channel IR reflectance sensor using an infrared LED and phototransistor to detect changes in surface reflectivity, generating an analog output voltage from 0–VCC. Operates at 2.9–5.5 V, with an optimal sensing distance of ~5 mm (up to 30 mm max), adjustable IR emitter brightness, and a 4-pin JST SH connector, designed for line detection, edge detection, and obstacle sensing in robotics and automation projects.

The Pololu 1300 programmer enables convenient programming and communication with AVR microcontrollers via USB in ISP mode. Thanks to an additional TTL port and the simplified oscilloscope function SLO-scope, it supports the debugging process of embedded projects, especially in systems based on Pololu robots and controllers.

Pololu Micro Maestro 1351 in kit version enables precise and flexible control of servos and sensors from a PC or microcontroller. Thanks to its ability to operate autonomously and function as a USB–TTL interface, it is used in motion control systems, animatronic projects, and interactive systems responding to external stimuli.
