Interfacing with hardware & Shrinkify arduino projects

http://arduino.cc/playground/Main/InterfacingWithHardware

So far there I have only experimented with a narrow range of electronic sensors and output methods. The link above is a set of libraries and instructions on how to interface with various hardware for example how to output NSTC or PAL composite to a TV http://arduino.cc/playground/Main/TVout and http://code.google.com/p/arduino-tvout/



This library interests me: http://liudr.wordpress.com/libraries/phi_morse/

Not only does it output morse code, but it also recognises morse code input.



It was intended to help people learn morse code.

This is a really great tutorial on how to 'shrinkify' arduino projects: once the code is uploaded to the chip (which costs under £2), it will run the code without the arduino board. This is further official documentation on it: http://www.arduino.cc/playground/Learning/AtmegaStandalone

xbee communication between two arduinos:

an option provided by 'building wireless sensor networks', but with a limited range.
