This project is a a very simple rain detector.
When a drop of water hits the rain sensor board overlapping two neighboring strips, they create a bridge where current can flow so the LED turns on.
Simple Rain Detector Schematic
When the two inputs of the rain sensor connected, (ie when a raindrop lands and overlaps two strips, current flows to the transistor turning it ON. When the transistor is ON, current can flow through the LED, lighting it up.

Every circuit here is a live project in Circuit Canvas, not just a picture. Copy this one and change a value, swap a part or move it to a stripboard: the schematic and the breadboard layout are linked, so a part added to one appears in the other.
Or start from a blank canvas and draw your own circuit, with thousands of ready-made parts.
