hello sir i m a newbie in robotics...Could u plz help me out by sending a
suitable ebook to make me feel abt robotics.....thanku.

Hi, Rahul;

first of all, let us 'locate' your basic skills. Robotics actually mixes some
fundamentals related to:

- electronics (analog and digital)
- control (automation)
- mechanics
- computing (programming)
- some others (ergonomics, A.T., etc.)

So, if you are a newbie for these very subjects, chances are that you should
search for books (and related knowledge) about them, too. With these areas in
mind, Robotics is just a matter of how to put them together.

The book I downloaded at www.booksbibin.tk is part if the bond between
programming and digital electronics.

Success!

HI,
I want to communicate with my AVR ATMEGA32 micro controller using USB port. I
have searched the internet but I have not found and easily understandable
information on internet.

Any one help me how to write the code on AVR for USB port using C or C++.
I also need help on code for computer side. on computer side C# and java
language programs are also helpful for me

Thanks in advance

Try to build analog line tracer robot (dont use micro), there is many source
scematic in the internet. This is the simply robot so it will give u basic pract
about robot parts

hi. i am also trying to communicate with an avr.i have some lead in it,usbasp is
an loader built on avr interface,i've gone through its headers it used an usb.h
header which might be helpfull .next in line is every usb device requires a
vendr n prodct id.u have to buy that.so we have to use a opensource version of
it names libusb. and try googling using "how to access usb?"..i will also try it
myself.
thank a lot

can anyone help me in building the usb programmer for avr controllers.
problem with the present usbasp from

http://www.fischl.de/usbasp/

is that atmega8-16pu aren't available in market.
Its fine if we get atmega8 anywhere in world, we would like to import them.
can any one help us please.
and any other usb programmers available can also be help full

If u have any document on embedded ethernet then please upload it

Hi Sunil,

Instead of building a programmer yourself I would suggest you to buy Pocket AVR
Programmer, you can find the details of it here..
http://www.sparkfun.com/products/9825

I have personally worked on it its great,  have used it for programming all
sorts of AVR while building projects & as well as for  uploading bootloader to
Arduino platform. As Mr. Udayan said Atmega 8 are available but not the new ICs,
the older ones have the problems of their own so we started importing
programmers instead building them. Easy Electronics is located in Basavanagudi,
Bangalore (our site is getting updated since we recently changed the server you
can still get to know more about us by visiting www.easyelectronics.in)

If you are interested & want to know more feel free to get in touch with us.

Hello there,
I am sultan and i have just recently join your group. I am a student in Pakistan
studying Avionics. I what to build a remote control of a robotic toy car,
therefore i need some basic information to start this project.
and secondly will you please send me a circuit diagram + items used in Wireless
remote control of a robotic toy car.
Keep up the good work.....
Regards
Shaikh Sultan Uddin

Please refer to the questions and topics already posted before askin
questions. Since many questions have already been answered.

Hi,

Thanks so much for your sharing about AVR.  I would like to download the book,
MY EXPERIENCE ON PARALLEL PORT INTERFACING to check my parallel port connecting
to AVR but not able to find it.  Can you guide me on where to download it? 
Thank you.

hi
  I am  working  on a sine wave generation project with a  ATmel 2560 micro
controller and a DAC.

  I want few input on how to go about  creating the  sine wave  table in 
program. Any help will be appreciated.
  I have more information that  could be either  email to  person interested or
would like more information  about code.

Hey Hasa,

Please check the maximum frequency that the DAC of the uC supports. It cannot be
more that a few tens of kHz normally. What do you need it for?

As to what concerns code snippets, start with a basic timer example. Then
overflow it every so often and output the new analog value to the pin.

Regards,
Mihai GALOS

Hi,
         I am trying to interface the MAX3421e as Host controller with
microcontroller. I am getting the Timeout error for Low speed usb device and J
state for high speed usb device.

Kindly tell me, why this error is coming?
