Using the Gravity Joystick Module V2 is a breeze. First, connect it to two analog inputs of your device. This will allow you to control your robot in the X and Y directions. The built - in switch, connected to a digital pin, gives you an extra control option. You can use the supplied cables and our IO Expansion Shield to connect it to your Arduino. Make sure to note that the new version has a different analog sensor port pin mapping. When it comes to voltage, this module can work with a supply voltage ranging from 3.3V to 5V. Keep it in a dry and clean place to maintain its performance. If you need more detailed information, check out the WikiDoc and Schematic provided.
