![]() ![]() Just as humans talk with fundamental frequency from 85 to 180 Hz (average adult male) or from 165 to 255 Hz (average adult female), every musical note is based upon a certain frequency. A buzzer can't understand code! It is instructed by the microprocessor to play certain frequencies according to our code. Our Arduino would be connected to a buzzer. If we look at lines 10 to 98 - those are the defined notes with frequencies (in Hz).Wanna have a listen? Here is the original song that I have butchered (for educational purposes). Now it's time to open the file Baianá_by_Bakermat.ino in this repository (or click here for it!). ![]() We'll be needing all these data in the next section. You know how the song goes, you have jotted down the notes too now time each note out and jot down the milliseconds (if you notice a 0M00S.00 format, you'll get something in 0.XY seconds, now multiply that by 1000, there you have your XY0 milliseconds!). How did I time these? Using the Stopwatch feature in my phone. On average, if you sing it out, DES took 0.27 seconds (270 milliseconds), PA also took 0.27 seconds (270 milliseconds), CI took 0.19 seconds (190 milliseconds) and TO also took 0.19 seconds (190 milliseconds). In the song Despacito, you might notice that the parts DES and PA are longer than the fast CI and TO parts. Some notes last longer, some notes last shorter. Getting The Note Durations Right - Approximation To see the GIF clearly, you may click here. You'll also see a decimal number being displayed upwards along with your note name it's not needed right now, so we'll visit that later. Even a sneeze or a snore has a note, so don't worry. You just need to hum into the microphone piece of your phone or hands-free and voilà! It tells you what each note is called, and you are ready to hold the humming notes for a while and jot the names down. You can do so using the Note Recognizer App (assuming you might have trouble figuring out musical notes instantly). Now you need to get down to the musical notes which will give shape to your code. Something which has tunes really stuck in your head. ![]() Hints - Jingle Bells, Hallelujah, Fur Elise or even Despacito. As it's your first time, settle on choosing one which has fairly less melodies, but which you really love. Let me debunk it for you here.įirst, you want to make up your mind about the song you are planning to make Arduino "sing" for you.
