Pololu Dual MC33926 Motor Driver Shield for Arduino POL_Female-Female Wires with Pre-Crimped Terminals The relays are SPCO (Single

The relays are SPCO (Single Pole Change Over) types

it is well suited to detecting the motion of people by their body temperature

you'll be able to program the Arduino controller

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 36 V and efficiently reduces it to 5 V

Pololu Dual MC33926 Motor Driver Shield for Arduino POL_Female-Female Wires with Pre-Crimped Terminals The relays are SPCO (SingleThis shield makes it easy to control two brushed DC motors with your Arduino or Arduino compatible board. Its dual MC33926 motor drivers operate from 5 to 28 V and can deliver a continuous 3 A per motor. These great drivers also offer current sense feedback and accept ultrasonic PWM frequencies for quieter operation. The Arduino pin mappings can all be customized if the defaults are not convenient, and the motor driver control lines are broken out
