Implemented by students from the robotics club of the Experimental Elementary School of Florina, during the 2015-2016 season. We followed instructions from WEDO Bots (
http://www.wedobots.com/2013/07/wind-turbine.html) with some changes for better stability.
The motor is controlled by a microphone that serves as a wind sensor (loudness). A Scratch program instructs the motor to spin faster as the wind picks up (loudness of the microphone).
