The Grove Mouse Encoder from Seeed Studio is a kit that uses a rotary encoder and a built-in mouse layout for elements, like up, down, left, and right and clicks, to add mouse related control to your project. It features two Grove Ports so that you can connect it to Arduino, Raspberry Pi, Microbit, or any other processor projects. The built-in mouse layout allows you to read data of direction and clicks from the rotary encoder. The kit includes a disc with 8 encoded pulses and an encoder magnet as well. You can use this kit to build projects like a steering wheel, mouse, or gamepad.
