Arduino Library for the Pololu QTR Reflectance Sensors
These connections give you access to the ATmega168
but the sensor module makes it possible to remap these pins or disconnect specific sensors altogether to free up I/O lines
including pull-up and current-limiting resistors
FSRs are sensors that allow you to detect physical pressure
Schrittmotor: bipolar, 200 Schritte/Umdrehung, 35 x 26 mm, 7,4 V, 280 mA hub-sensoren Arduino Library for the PololuThis hybrid bipolar stepper motor has a step angle of 1. 8 (200 steps revolution). Each phase draws 280 mA at 7. 4 V, providing a holding torque of 650 g cm (9 oz in). The motor has four color coded wires with bare leads: black and green connect to one coil, and red and blue to the other. It can be controlled via a pair of suitable H bridges (one for each coil), but we recommend using a bipolar stepper motor driver. A 5 mm universal mounting hub
