The Gravity Sound Sensor is used to detect the sound intensity of the environment. The DFRobot Sound Sensor is an analog sensor and only need a dedicated data line. The sensor can be extended with the Arduino board, in combination, it is very easy to achieve the sound perception associated with the interaction effect. Definition of the sound sensor pin: 1- Signal Output 2- GND 3- Power. Sound sensor interface socket for PH2.0.
Good news: Nice to have been sent the version 2 of the DFRobot Sound Sensor. The bad news is that the cables and connectors supplied with V2 will not work with older DF modules directly. The Vcc and Gnd pins have been swapped in the version 2 Sound Sensor boards. Poor silk screening, layout does not clearly indicate which pins are what. You will have to go to the DFROBOT site for that.
