| + | 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> | ||

| - | At first I defined some important elements (the buzzer, the keyboard corresponding LEDs, the modes implemented on the Arduino Uno breadboard and some musical notes). | + | In setup am setat intreruperile pe pinii pe care aveam butoane. |
| - | I also used 2 timers, one in order to control the leds and one for the buzzer. I added external interruptions, one for the switch button and one for the start/restart button. | + | In loop, in modul guided al pianului am aprins ledul corespunzator notei care trebuie apasate. |
| - | Then, in the loop() function, I implemented the 2 modes of my smart piano, using the getNote() function and learnSong() function. | + | In functiile ISR am preluat intreruperile de la butoane si am cantat nota corespunzatoare butonului folosind tone sau am schimbat modul / melodia. |
| - | The getNote() function is used in the FREESTYLE MODE. When the user clicks on a key, the corresponding LED will light and the buzzer will sing the correct note. | + | Melodiile alese au fost scrise in intr-o singura octava. |
| - | The learnSong() function will teach you to play a song. All you have to do is to click on the keys that have the LED turned on. You will learn to play your favorite song in just a few minutes. | + | Am definit notele muzicale folosite si de asemenea o variabila tempo pt a face pianul sa cante mai incet sau mai repede dupa preferinta. |
| - | 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. | + | Functia sizeof returneaza numarul de bytes, fiecare valoare int este compusa din 2 bytes (16 bits). |
| + | Variabila wholenote calculeza durata totala a unei note in ms. | ||
