Introduction: Motion Controlled Indoor Wind Chime

About: I am an American teaching English at Shangluo University, Shaanxi. I like making machines that do interesting but fairly useless things - I call them Quixotic Machines.
I use an Arduino Uno to control a servo to pull the clapper on a wind chime. An ultrasonic sensor detects movement. Should really use an IR sensor but it works. The servo has a separate 6 volt power supply and the Arduino is powered by wall wart. Pretty simple project. Will be using the wind chime in a future project.
