This slide potentiometer is a linear variable resistor with a total resistance of 10k. When you move the lever from one side to the other, its output voltage will range between 0 V to the VCC you apply. Three of four Grove pins are connected to VCC, GND and the ADC IN on the slide, while the remaining pin is connected to a green indicator LED. You can use the indicator LED to visually display the change on the potentiometer.
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.
