Introduction

I want to thank you and congratulate you for downloading the book, Arduino: A Comprehensive Beginners Guide .

In this ebook I m ging t explain th basic lmnt f Arduino brd. W r ging to nwr th fllwing utin: wht i Arduino? Hw did the rjt trt? Wht does it mk Arduin diffrnt?

If u wrk with rtting brd, u hv t come across Arduin. Arduin is a hea rtting brd dignd fr ntrlling bjt nd interactive tm. It usually costs u $30 to $50 to obtain n. Th board u an Atml mirntrllr with dditinl ltrni components to mintin th vilbilit and durbilit f th computing unit. For instance, Vltg Rgultr. Th brd uull requires 5 vlt to operate. Th voltage regulator rgult th inut vltg nd llw rviding frm 5 t 12 vlt. The board i n ur nd all digrm are ublihd undr creative mmn lin.

On f the most important aspects of Arduin is that it i standard nntivit. Th brd uull has 16 to 48 I/O in. Sm f thm r digital. Other are dignd fr nlg input vltg murmnt. Furthrmr, m of th digitl I/O n gnrt ul-width modulation single - also known as PWM.

Th Arduni i nt only hardware n ur. It i software t. Arduin h a fr open source intgrtd development environment (IDE). Th IDE llw u writ nd uld ur litin to Arduino brd. The programming lngug of Arduino is bd solely on 'Processing' rgrmming lngug. With a fw lik nd ul lin f codes, u will b able t uld ur application t the brd.

The Arduino has a vibrant mmunit. You hv lnt of l t ask nd thousands f thund f wbit t search. In dditin, th team h dumntd th Arduin perfectly. Evrthing is wll xlind nd mrhniv. Aing th required dt i rltivl frm thir ffiil wbit.

Chapter 1

W ht I Arduin? A Brif Lk at th Arduin Pltfrm

Arduino i n open-source, rgrmmbl mirntrllr nd software based n the ATMg hi. Althugh th Arduin i designed a rtting ltfrm, it n b ud in vriu ltrni rjt whthr tmrr r mbddd. Th Arduin brd n b programmed uing th Arduin software. The ntx fr thi i similar t C/C++ and Jv. It is designed to b iml nd t u, and can b rtd by nn, frm beginners to xrt alike.

A Arduino i an n ur ltfrm, you n get hold of th source d and schematics fr it. Thi mn u n delve as fr int it as you want, vn rting ur own Arduin boards. There i also a lrg mmunit bhind it, nd you n find mn tutorials and rjt frm ll vr th wrld nlin.

Wht can I d with an Arduin?

Prtt muh nthing you want! It h bn used in so many diffrnt w th tin are virtull unlimited. Past rjt have included rbt, rt intlltin, in-r mutr, MIDI controllers, cocktail mkr, humn-mutr intrf, Facebook 'lik' untr, advertising dil, lk, mui intrumnt, utm mouse nd kbrd, hm utmtin... The lit g on and on!

Th min ftur f an Arduin board are it' bilit t rd dt from sensors, t nd and receive digitl signals nd n connect vi serial t ur mutr. Yu n control mn thing, frm LED nd LCD, t mtr nd rl. Yu n also rd values frm nr uh potentiometers, light dependent ritr (LDRs) and iz.

Th digitl in n n Arduin llw u to read r writ 5v values. Yu n use a pin t turn n an LED (with a ritr). Yu n nd a signal t a relay t operate higher vltg lin lik tlviin nd hu light. You n nd messages t mtr to turn on nd off. Yu can check t if a button h been pressed. Yu n even nd nd riv ril dt, rlll dt nd digital ul width modulation. Bill nthing tht can b ntrlld vi a bit f current n be ud.

The analog in allow u t read n inming voltage btwn 0v and 5v. Thi will be hw u rd frm nr. There r a multitude of nr vilbl, frm simple hnd-n rur nr nd rotary potentiometers, to environment sensors uh pressure, g, tmrtur nd vn alcohol. If u have, for example, a lidr set to xtl hlf of it rng, it huld utut a vltg f 2.5v. Th Arduin n thn rd thi nd u th vlu t ntrl mthing l.

Yu dn't hv t stop with just ntrlling ltrni iruit. Yu n nd dt back t th mutr t ntrl ftwr uh Processing and Max/MSP. You can nd th data vr USB with mt mdl. Sm models hv Blutth and Ethrnt rt, and with n dditinl hild (lik n dd-n unit) u n mmunit vi WiFi and other rtl.

Wht can't I d with n?

The Arduino doesn't hv a lt of ring power in it, rtt much n mjr intensive tk i out f th utin. Yu won't be bl t process, rrd or utut video r udi (Althugh u n output grhi to TFT r LCD screens). It is nt lik a mutr. Yu wn't b bl t hook up ur wbm r kbrd t it. Thr i n rting tm with a GUI (lik a Rbrr Pi). It i a completely different beast.
