Arduino to processing

So I have a Sharp IR sensor connected to my Arduino, feeding to my pc the values of its analog input, via the Serial connection.

To do this, I'm using the Serial.write() command. I want to be able to read these values into processing, but when I use the Serial.read() command in Processing, the values it picks up are nothing like what the Arduino Serial monitor is giving me, and are unaffected by the IR sensor.

What am I doing wrong, and how can I get processing to read these values from the IR sensor?

Any help is appreciated.

Bluetooth control from your Android phone or tablet

Hello, I am the author of Mintoris Basic for Android phones and tablets.  I recently added Bluetooth serial communications to the language with the intention of making it very easy to communicate and control robots.

Here is a short example program in Mintoris Basic which connects to a device then transmits data from the phones accelerometer.  So as you tilt the phone or tablet in any direction, the amount of tilt is sent to the Bluetooth device.

dim a$(0)
dim c(4)

' Get a string array of all the paired Bluetooth devices

a$()=BTGetPaired$()

Bluetooth Dongle Comms

This is an Open Source, Collaberative project blog.

The aim is to use commonly available Bluetooth USB dongles to enable a PC to control a free roaming robot.

In my case the missing link which I have been trying to get working since about 2001.

The idea is to have an autonomous PC controlling the robot remotely (WITHOUT A CONNECTING WIRE ), so that I can test some rather radical Artificial Intelligence ideas that I have.

Bluetooth dongle comms

Hi All

I am busy planning a platform (400mm x 400mm) for a couple of experiments (mainly AI) that I would like to do.

I intend using a PC as the brains (program in C++, VB or whatever) BUT the platform must not be connected using wire.

Therefore there needs to be bi-directional RF communications between the platform and the brains.

As I am Electronically Challenged (to put it mildly), this is where I am stuck.
