try retstoring your os. i mean it.
on start menu search for the system restore and restore it to a previous day.
i guess there's no problem with your board.

Each bluetooth device is a separate serial port.
so two rn 42 slaves will be on two serial ports?

i asked about the mac address of the bluetooth device thats the rn 42.

matlab is able as its addressing the port and the port is connected to the bluetooth tx.
my doubt is since there is only a single port to connect and two bluetooth devices are there (ie, the arduinos),
is it possible to address the recipient using the mac address or anything., if any?

i'm sorry if its not clear,
i need to send control signals to two leonardo based robots at the same time,
i have rn 42 modules fixed on board.
no need of two way communication,
just to receive the commands from the laptop.

hi i want to coonect two arduino leonardos as slave to the master, a laptop.
i've got two RN 42 Bluetooth modules and two arduino leonardos.
is it possible to connect two arduinos as slaves?
i am using MATLAB to do this.
6  Using Arduino / Installation & Troubleshooting / New to Arduino : What is the Programmer Menu in IDE for? on: January 03, 2013, 04:32:21 am
Hi,
I'm new to Arduino.
I have 2 Leonardos.
i want to start working with them, btw i was exploring the IDE last two days,
I Saw a sub menu in tools named programmer.
what this menu is for?
does this have anything to do with arduino leonardo?
which one should be the default one if i'm just using my leonardo straight to my computer?

Take a look at this http://docs.opencv.org/doc/tutorials/imgproc/imgtrans/hough_lines/hough_lines.html
This code should work for you, but you'll have to read a webcam image instead of an image file. Then you'll have to send the line info, via serial, to the arduino and write a program to turn the motors based on the data.

thanks for the tutorial.
but as I'm a starter in OpenCV, Let me know what's gonna be the output (of the processed image?)
can i assign it on a variable to work with the further programming? smiley-roll

What kind of track is it? Is it an open area or a sort of maze? Because you're idea is not that easy to realize. If it's a maze or something like that, then its easier to use a ultrasonic sensor or a line-follower.

The track is a sort of zebra line, i guess it can't be done using a line follower cuz the lines are perpendicular to the robot's path
9  Using Arduino / Interfacing w/ Software on the Computer / Leonardo and MATLAB interface? on: January 01, 2013, 12:29:05 am
hi,
i have a doubt about the interface between Leonardo and MATLAB.
in the MATLAB Arduino IO package documentation the supported Arduinos shown are Arduino Uno,  Mega 2560, or Duemilanove ,
as Leonardo is not there on the list, let me know whether there is any incompatibilities between
MATLAB and Leonardo?

thanks

thats really great
would you gimme an idea how to track the track and navigate the robot?
11  Topics / Robotics / Re: Robot control using top camera image analysis? on: December 31, 2012, 04:55:34 am
thank you! but I'm restricted to use only  MATLAB/C++/OpenCV.

i can't really help myself to get to a point,
how to move the robot forward(just sayin.) ?
my approach is as below.,.


1. keep a red/green colored arrow on the top of the robot (prob. a sticker)
2. Use MATLAB/OpenCV/C++ (Development Environment doesn't matter ) to track the position of the arrow.
3. Compare the arrow's position with the predefined arrow image and the track.
4. Rotate the respective motors and check the position of the arrow till it come straight with respect to the path.
5. if everything comes straight, move the robot forward.

does anyone have any  ideas or suggestions?
thanks again.

Hi all,  smiley
I'm New to Arduino and Arduino community.
Yesterday they delivered my very first Arduino (Leonardo x 2).
I'm into a project where a top camera image is to be analyzed and my Leonardo based robot is to be navigated as per the analyzed image,
using MATLAB, C++ and OpenCV,
does anyone have an idea how it can be done?
i have a RN-42 bluetooth module from sparkfun to interface Arduino with MATLAB running on PC,
thank you smiley
