Rain Detector

It rained all day and night for the first day and night of the Asian Games. I got out my Rain Detector Kit to see if it was raining. The rain detector works by using water in a glass (gathered by the rain) to complete a circuit and causing the Piezo Transducer to emit a noise when electricity runs through it (see schematic, below) .
