Arduino revolution

Yesterday I visited Arduino website and found a change in their main web page, so I continued to read their blog and found some interesting alteration
that I can summarize to you as below…

arduino

Arduino new revolution

1. Arduino has a new logo (as you can see in the picture above). I thing it is “Atom” or “Infinity”. The new logo is easy to remenber than the old logo.
2. Arduino.cc will open their own webstore on 18 October, this year. New webstore will eliminate the difficulty in ordering arduino board that made by
Arduino.cc. In the past , they sold their arduino board via distributors or electronics shop only. There’re many electronics shop in the world that sold
arduino board (some shops sold real board while some shops sold clone board). For this reason the people may confuse about how to find the electronics shop
that sold the real arduino board of Arduino.cc.

3. They released the new arduino board named “Arduino Uno” and “Arduino Mega 2560”.
Both board still use AVR chip as their main processor.
(Arduino Uno use ATmega328 as main processor while Arduino Mega 2560 use ATMega2560 as processor).
Arduino Uno is special board that replace ft232 chip (FTDI USB-to-serial chip) with ATmega8U2 (8-bit microcontroller with Programmable USB
controller).
4. They launched Tinker Tookit, the new sensors development module that can connect and use with arduino board.
5. They plan to release Arduino Ethernet board. This board isn’t the ethernet shield but it is board that include ethernet interface equipment
(such as ethernet chip , ethernet port , etc) into main PWB. So in the future , user can upload program to the board via ethernet
interface (this feature is exist in mostly embedded linux board that you can upload anything to the development board via FTP or TFTP).

To view more information , please visit Arduino.cc website and Arduino.cc blog.

I am the one who like Arduino so much and I hope this change will bring a lot of good things to Arduino developer and Arduino user all over the world.

Thank you,

More on Arduino part I.

More on Arduino part one.

Arduino-tone
It is the library for produce square-ware tones.It can use with ATmega8,ATmega168/328 and ATmega1280
microcontroller series.With this library,you don’t need to use DAC (Digital to Analog onverter) for building the
tones.This library use timer and PWM of microcontroller, so it will affect the usage of other PWM outputs.

Dataflash
It is the library for make your Arduino be able to interface to the external memory chip.It’s suitable for
use in storing the voice file or use in datalogging application.The original code of this library is come
from Atmel butterfly.

Arduino contest
Finished contest from Instructables website.This contest has a lot of interesting Arduino projects and
also contain the instruction to describe about how to make each project too ( but I don’t know that it give the
source code relate to each Arduino project or not).

ArbotiX Robocontroller
It is control board for robots.It use AVR (ATMEGA644p) as main microcontroller and also contain the Xbee module in order to communicate with the robot by wireless radio signal.The designer of ArbotiX board also designed the library that used for interfacing with the motor of Bioloid System (this will help in controlling the motor easier).This board can be used with various Bioloid motor series (Bioloid motor is “digital servo” motor, it can be commanded via RS485 or even can communicate via Xbee too).

Multi-touch Technology

This technology is very interesting.The person who inspire this technology is Jefferson Y. Han.He is researcher at NYU (New York University).To know more about him, please visit these links.

This is Multi-touch presentation video.



The theory that used in Multi-touch is Total internal reflection.

Arduino FAT

Nowadays Fat storage device has an important role for Embedded System.Many
electronics manufacturers also integrate the unit for read Fat file system with their
products such as digital camera , mobile phone , MP3/MP4 player , GPS receiver , etc…

There are many storage device on the market that use Fat file system such as harddisk,
SD card,MMC card,SDHC,Micro SD card,Mini SD card, etc. This article mention about
only SD card.

SD Card (Secure Digital Card)
It is storage equipment that use nand flash memory to store the data (non volatile
memory).SD Card was developed from MMC card.Its body is slightly thicker than MMC card.
It can have a capacity up to 4 GB while MMC card has a maximum capacity of 512 MB.The
speed of reading and writing of SD Card is faster than MMC card.Furthermore SD card can
be locked to disable any data-writing to the card by implement security system to the
card.SD Card also has high capacity version called “SDHC”.SDHC can have the capacity from
4 GB – 32GB.Mini SD or Micro SD card also has the same principle as SD card but its size
is smaller than normal SD card.

OK, now back to the story corresponding to this article topic “Arduino FAT”. For
anyone who want to develop FAT project and don’t want to spend too much money I
suggest you develop your project with Arduino because its development enviroment is very
cheap (the board and programmer is cheap and easy to find, the compiler is free).Below is
the resource on the internet that concern with FAT project for Arduino.I think they are
practicable up until now.

1.S65-Shield
It is SDFAT library for arduino to make vfat sd-card (library of SDFat is come from
elm-chan project).

2.Arduinonut
Another Far file system for Arduino that use u-fat file system.
