Everyone is making things connected with twitter. The arduino environment makes many people easy to interface hardware to the internet.
there’s really not a whole lot of hardware involved (so far):
- arduino duemilanove
- adafruit ethernet shield
- WIZnet ethernet module
- mercury switch
- perfboard, wires, cables, misc. bits
Arduino ethernet interface
The arduino ethernet interface is very simple (in theory). the shield is simple and quick to assemble, and the wiznet module just plugs in to it. the shield then attaches to the arduino.
There were a couple of modifications i needed to make. i added female connectors (such as the ones found on the arduino board itself) to the pin pass-through connectors; i don’t know why any connectors didn’t come with the shield. i also moved the reset wire to the same solder joint where it connects with the under-board pin, so that i could fit an entire row of connectors in.
