Make your umbrella lighting in the rain. Let’s have the Grove – Logic DC Jack as the controller, which is the powerful brain of your project, Grove – water sensor as the input and EL Wire as the output. After complete connections, the EL Wire-Green will light up when there’s water falling on the sensor. See the principle as below and check our Recipe for step-by-step tutorials. Listen to the rhythm of the falling rain, and wait for the magic to set it aglow.
