The buzzer inside or speaker on M5core will exhibit the key value, so instead of using a keyboard, you can make a fruit piano.\u003c\/p\u003e\n\u003cp\u003eThis Unit communicates with the M5Core via the GROVE A I2C(0x51).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstructions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e1）Use the buzzer on the unit to exhibit sounds:\u003c\/p\u003e\n\u003cp\u003eTake a Dupont wire(male to male), one end plug into GND, hold the other end to your hand.
