The experiment is for switching an acoustic sounder as a rain alarm after a predetermine time. It may, however, be tinkered for a number of other applications. Needless to say, this is a simple ...

That’s what the folks behind ArduSat are doing: they’re launching an Arduino-laden satellite into orbit with a bunch of sensors to enable anyone to become a citizen space scientist.
