Lab7 การใช้งานลำโพง

จุดประสงค์การเรียนรู้

- สามารถใช้โปรแกรมArduino IDEสั่งงานความถี่เสียงของลำโพงบัซเซอร์ผ่านบอร์ด Lutus Nano Bot ได้

อุปกรณ์ที่ใช้

- บอร์ด Lotus Nano Bot

ในตัวอย่างนี้เราจะใช้ลำโพงบัซเซอร์ต่อเข้ากับพอร์ต 3 ของบอร์ด ดังตัวอย่าง Code

ตัวอย่างที่ 1 การใช้งานเสียงดนตรี 1 ตัวโน๊ต

Arduino IDE Code

void setup() {

tone(3, 1500, 5000); // คำสั่งเสียง tone(พอร์ต,ความถี่,ความยาวเสียง)

}

void loop() {

}

ตัวอย่างความถี่ตัวโน๊ต
