Let your Arduino tweet without an Ethernet shield

Although using an Ethernet shield with your Arduino to send tweets is convenient and allows autonomous tweeting without a host PC, to save money Iain Foulds has described a method for an Arduino to send tweets by instead using an Internet-connected PC. To do this, a simple Python program is run on the host PC - which tweets any text received from a USB-connected Arduino board.
