Two direction movements will output different analog signals as they are actually two potentiometers. The resistor is ~10k for each. The joystick also has a push button that is could be used for special applications. When the module is in working mode it will output two analog values representing two directions. The value is restricted in a little smaller range (e.g 200~700)compared to the normal joystick, while it is around 1023 when the button is pushed, so that the MCU can detect the action of pressing. **Features** Grove Compatible, with 4pin universe 2.0mm connector 5V/3.3V Compatible Analog Output(Maximal value will be got when the button is pushed) For all Grove users (especially beginners), we provide you guidance PDF documents.
