This module is an incremental rotary encoder. It encodes the rotation signal from the axis and output the signal by electronic pulse. The Grove – Encoder is one of the Grove series and has a standard Grove interface.
When you need to add a rotary knob to your project, for example a volume knob for a speaker, a selection panel or a digital input, this will be your first choice.
It is able to generate another signal when it’s being pressed down. However due to the limitation of the number of Grove signal cable, the module is made without output of this signal.
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.
