User Manual

What is Arduino®

Arduino

is an open-source prototyping platform based on easy-to-use hardware and

software. Arduino

boards are able to read inputs – light-on sensor, a finger on a button or a

Twitter message – and turn it into an output – activating of a motor, turning on an LED,

publishing something online. You can tell your board what to do by sending a set of

instructions to the microcontroller on the board. To do so, you use the Arduino

programming language (based on Wiring) and the Arduino

software IDE (based on

Processing). Additional shields/modules/components are required for reading a twitter

message or publishing online. Surf to www.arduino.cc for more information.

Product Overview

This motor shield contains two motor drivers and a 74HC595 shift register and extends the

pins on the Arduino® from 3 to 8, which allows controlling the direction for the motor

drivers.
