Another little experiment. I took a little button and wired it up to the arduino. Set a little timer on it so that it would only register button presses if there’s at least a 20 second pause between button presses. When the button is pressed and the timer says it is ok, a processing application sends email. The way my code is written it could be a signal from any number of sensors and could send to any number of email addresses. Pretty neat all round.
No picture of this one.
