Arduino Labs V2 Dated Dec 20,2009

Why ArduinoIt is low cost - Just Rs 1000/- gets you started.

It is easy - 1 hours on PC and you are confident.

It is open source - nothing is hidden.

It is multi platform - Windows, Linux, Apple Mac OSX

It can create complex applications/products.

Simple LabsLab 1 deals with just one LED, start with a simple blinker to code that says SOS or SMS (morse code)

Lab 2 deals with serial port or interface computer with Arduino Port

Lab 3 interface GPS device and computer where location is sensed and displayed lat/long/time info on serial port

What will you learn

Basic Grammer, Simple commands

Communication between 2 devices (computer and embedded unit)

Communication between 3 devices (complex embedded unit, simple embedded unit and computer)

What NextInterface simple other devices

- Alpha numeric devices

- Key board and Digital Display

- Real Time Clock

- Relay and Opto couplers

- Temprature, Current, Voltage

- DTMF Signals

After That

Integrate Multiple Devices

Add user interface / sequence

Create a real life application that inspires you.

Material Required

Computer with Linux/Windows/MAC OS with RS232 port

Arduino Board with pre-programmed ic with boot loader

+12V Power Supply

RS232 Cable

InstallationDownload and Install latest version of Arduino software (017 as on Nov 2009)

Connect Arduino board with power supply and RS232 port.

Note the mcu on Arduino and Serial port of computer

Run ARDUINO. Select board and port from tool menu.

Arduino Pin NumbersArduino board has 20 I/O lines.

Numbered from 0 to 19

All are general purpose I/O

Some has additional functions

Pin 13 is LED on Board. It glows when pin is HIGH and off when LOW.

Some Common WordsSketch - Program that runs on the arduino boards.

Digital - Only two values 1(HIGH) or 0(LOW).

Analog - Multiple values (like volume, light intensity) Usually has a range from 0 to 255.

Pin - input or output connected to something like switch or led.

More Common WordsPort - Serial port on which arduino is connected for uploading the program (sketch).

Bootlaoder - Like OS. A program that starts first. Wait for new user program. If nothing received then start the existing user’s program.

Upload - A process done at computer that sends the user program via serial port to Arduino.

Just Remember

Select proper com port (Tools | Serial port)

Select proper board (Tools | Boards). For version 1 it is Arduino NG or Older with ATMEGA168 (some may have ATMEGA8)

When uploading ensure that Hyperteminal is disconnected or close.

Common Queries

I am doing MCA. I have no Idea about elecronics.

- That’s okay.

- There is no electronics more than you have in PC.

- In PC you connect key board, mouse, pen driver, external HDD/CDROM, modem or Monitor.

- Here also you may connect some boards like GPS or GSM or Display.

Common QueriesThis is too simple. I plan to work on sound analysis or TCP/IP protocols

- That’s okay.

- Inital labs deal with leds and serial port.

- Very soon you will be able to connect to a server via TCP protocols or connet to ethernet or control a complete elevator with this board.

- By the way the speed of this board is more than 3X of that of IBM/PC - first popular computer that you may remember

Common QueriesThis is only for hobby

- Yes, this is for hobby.

- And at the same time, it is used for commercial and power ful application.

- Some application that we have installed are remote monitoring of Mobile Phone Towers and Traffic Timers.

- Check on web, you may be able to find lot more serious application than hobby applications

Common Queries

This version is with RS232 and only for Desktop

- This is an entry level model costing Rs 1000/-

- Next model with USB connectivity is also available.

- More models with memory upto 128kb and I/Os upto 50 are available.

- They of course cost more. Yet the same programs will work on them as it is.

Common QueriesDo I have to buy boards from you.

- The complete details including PCB design, circuit diagram are available from arduino.cc.

- All parts as well as complete boards are available in local markets in India.

- On line training is open and free.

- Personal training is available from various sources and is paid. There is nothing extra that is not on website.
