Build your own rain-water alarm!

How annoying is it when there are clothes hanging out to dry and it suddenly starts to rain?

You have to rush outside to help bring the clothes inside before they're all soaking wet again. Now imagine you can build a rain-water alarm which can set off a buzzer with the very first rain-drops. And imagine you can do this with just a few electronic circuit components!


In this video tutorial Mr Donald Vella will show us just how this can be done!
