Analisis Kode Nada Buzzer Arduino
Published:
Potongan program di atas mendefinisikan output nada (KETIK TANPA SPASI)....
Answer: [________]
This question includes visual content: The image shows a split screen of a Wokwi-like Arduino simulator. On the left side is a code editor labeled 'sketch.ino'. The code defines frequencies for musical notes: DO (262), RE (294), MI (330), FA (349), SI (494), and DO1 (523). It sets a buzzer on pin 9 using 'const int pinBuzzer = 9;'. The setup function has 'pinMode(pinBuzzer, OUTPUT);'. The loop function shows 'tone(pinBuzzer, SOL, 500);' though SOL is not defined in the visible header lines. On the right side is a simulation panel showing an Arduino Uno board connected to a piezzo buzzer. The red wire of the buzzer connects to Digital Pin 9, and the green/black wire connects to GND.

Mari kita perhatikan potongan kode pemrograman Arduino berikut ini untuk mengetahui nada mana yang sedang didefinisikan sebagai output.
Menganalisis Kode Arduino
Pertama, mari kita lihat bagian definisi nada di bagian atas kode. Di sana terdapat beberapa konstanta frekuensi untuk nada do, re, mi, fa, si, dan do tinggi.
- #define DO 262
- #define RE 294
- #define MI 330
- #define FA 349
- #define SI 494
- #define DO1 523
Sekarang, perhatikan baris kode di dalam fungsi loop pada baris dua puluh empat. Di sana terdapat fungsi tone.
Sintaks fungsi tone adalah pin yang digunakan, diikuti dengan nama nada, dan durasinya. Pada kode tersebut tertulis tone buka kurung pin buzzer koma sol koma lima ratus tutup kurung.
