WHAT IS AN ARDUINO?Sunday, September 12, 2010
WHAT IS AN ARDUINO? Arduinois an open-source electronics prototyping platformbased on flexible, easy-to-use hardware and software. It'sintended for artists, designers, hobbyists, and anyoneinterested in creating interactive objects or environments. Alittle programmable computer platform designed helppeople “make things go.”http://www.arduino.cc/Sunday, September 12, 2010

HARDWARE Basedupon widely available 8-bit Micro-controllers Single-chipComputers as powerful as the early PCs.but cost much less OpenHardware Schematics Kitsand board designs freely availableand Built-up Boards from 15 to 80Sunday, September 12, 2010
HARDWARESunday, September 12, 2010
HARDWARE 19pins, each can be either Input or Output 6can be PWMed (digital dimmer) 6 Analog 13Digital pins 6V-12V Easilypinsexternal Power Supply or from USBExpandable & Customizable to add features Think “C/MRISunday, September 12, 2010on a chip” with extras
SOFTWARE Works Openwith Windows, Mac OS X, and LinuxSource Freeto Download & Use Easyand fast to use ProgramSunday, September 12, 2010via USB
SOFTWARE C-likeLanguage Programs Rapid Can Easyare called “Sketches”Prototyping of small projectsdo useful things in 1 or 2 pages of codeto use “Libraries” developed by others DCC, Communications, motorSunday, September 12, 2010control, LED dimming etc.
SOFTWARE Allthe “grunt work” is done for you by Arduino, which hidesmost of the complexity (remember, it was designed for artists!) Onlytwo functions to worry about setup loopSunday, September 12, 2010: initialize inputs & outputs: run over and over again until power is removed
/*Blink: Turns on an LED on for one second, then off for one second, repeatedly.* LED connected from digital pin 13 to ground.* Note: On most Arduino boards, there is already an LED on the board connected topin 13, so you don't need any extra components for this example.Created 1 June 2005By David d on an orginal by H. Barragan for the Wiring i/o board*/int ledPin 13;// LED connected to digital pin 13// The setup() method runs once, when the sketch startsvoid setup(){pinMode(ledPin, OUTPUT);}// initialize the digital pin as an output:// the loop() method runs over and over again, as long as the Arduino has powervoid loop(){digitalWrite(ledPin, HIGH);delay(100);digitalWrite(ledPin, LOW);delay(100);}Sunday, September 12, 2010// turn the LED on// turn the LED off

BLINKING LEDS WERE EASY. What How Canabout something more challenging?about doing something with the user’s INPUT?we make noise? Maybeeven Annoy The Neighbors?Sunday, September 12, 2010
DANGERSHIELDAn Arduino add-on.buzzertemperature & light sensorsIt's got a variety of electroniccomponents that you can useto do fun and useful things:linear slidersLEDs (of course!)A excuse to learn by playing!Sunday, September 12, 2010pushbuttons

NEED SOMETHING MORE“RAILROAD RELATED”? Allthese were simply fun ways to learn while playing Thereal fun begins when you apply these lessons to yourlayout!Sunday, September 12, 2010
CP MICHAEL Takethe “best of ” Loconet, C/MRI and Arduino and try tobuild a control point for the layout, similar to those used bythe “big boys”, without having to have a computer runningthings.Sunday, September 12, 2010
GOALS Talk “Code ControlLine” to other nodespackets from dispatcher’s cTc machine Indication Usepackets from the Control Point field unitsLoconet to talk to the devices in the interlocking (Future)Sunday, September 12, 2010use NMRAnet as the Code Line.
