Description: A piezo buzzer connected to the Ground (GND) and D9 pins on the Seeeduino Xiao plays a basic tone in G.
Supplies:
1 – Breadboard 400 Points
1 – Seeeduino Xiao
1 – Piezo Buzzer
Arduino Code:
const int speaker = 9; void setup() { pinMode(speaker, OUTPUT); } void loop() { tone(speaker, 277); // Send 277KHz sound signal, which is a G tone delay(1000); noTone(speaker); // Stop sound delay(1000); }
