This is a simple yet enjoyable twig to use. The piezo can be connected to digital outputs, and will emit a tone when the output is high. Alternatively it can be connected to an ana log pulse-width modulation output to generate various tones and effects. For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product. Documents: Please visit SeedStudio wiki page for more info about this product.
