 ====== Arduino's Smart Piano ======

+<note tip>This project will simulate a smart piano using an Arduino breadboard.
+Besides implementing a simple piano, where you can play any song you want (in the limit of an octave because I only manage to connect 8 pushbuttons as keynotes), I came up with the idea of creating a special mode for those who do not know how to play the piano.</note>
 ===== General Description =====
-<note>The smart piano will have 2 operational modes:

 For this project, I used:

   * 10 red push-buttons, 8 corresponding to the notes for each degree of the scale, a switch mode button and an on/off button
   * 8 white LEDs
   * 1 passive buzzer

 <note important>In Fixed do, each syllable corresponds to the name of a note. In the major Romance and Slavic languages, the syllables Do, Re, Mi, Fa, Sol, La, and Si are used to name notes the same way that the letters C, D, E, F, G, A, and B are used to name notes in English.</note>

 ===== Software Design =====
-My program contains the basic arduino functions setup() and loop() and some other more like getNote() function and learnSong().
+In setup am setat intreruperile pe pinii pe care aveam butoane.
-I used only 2 analogical pins for all the 8 pushbuttons correspoding to the keyboard, so that at first we are obliged to find out the corresponding values of every button. Based on what is displayed in the Serial monitor from A0 or A1, we can deduce what note has been pressed.
+In loop, in modul guided al pianului am aprins ledul corespunzator notei care trebuie apasate.
+In functiile ISR am preluat intreruperile de la butoane si am cantat nota corespunzatoare butonului folosind tone sau am schimbat modul / melodia.
+Melodiile alese au fost scrise in intr-o singura octava.
+Am definit notele muzicale folosite si de asemenea o variabila tempo pt a face pianul sa cante mai incet sau mai repede dupa preferinta.
+Functia sizeof returneaza numarul de bytes, fiecare valoare int este compusa din 2 bytes (16 bits).
-I also used 2 timers, one in order to control the leds and one for the buzzer. I added interruptions, one for the switch button and one for the start/restart button.
+Variabila wholenote calculeza durata totala a unei note in ms.
