In this free workshop at Patten Free Library, you will create an invisible xylophone that beeps a tune as you wave a wand!  In the process, you will learn to arrange graphical computer code that allow sensors on the wand to control a speaker. You’ll have fun decorating the wand to express your own personality!  Open to residents of the library service area in grades 6-8. Register with the reference desk pflreference@patten.lib.me.us .
