 == The Directional Coupler ==
-I'm just about organizing the hardware.
+Hardware is ready. I managed to find a wonderful Directional Coupler on Ebay. This coupler produces two RF AC currents. One for forward, the other for reflected power. I am leading these currents through diodes into an [http://www.sparkfun.com/commerce/product_info.php?products_id=8883 ACS712 Low Current Sensor], which produces a voltage between 0V and 5V. This voltage again can be measured by the ADC in the Arduino.

 My first steps on the Arduino platform are successful! Since I have been working on a Ubuntu Hardy platform, I noticed that I would not be able to compile my programs properly because there are some bugs here and there. Anyway, so I decided to upgrade to the most modern Ubuntu Jaunty distribution and now it works fine: I can start the Arduino development environment without problems. Trying out the first little program, the famous "Blink" program which blinks a LED, compiled perfectly. So I started over and plugged the LED into digital output pin 13 and GND and uploaded the code and there it went. The Arduino went blinking!!!
