Qhov "Piano" no tuaj yeem ua suab paj nruag octave ntawm piano tiag. Kev nias cov nyees khawm yuav sawv cev rau qhov nias tus yuam sij ntawm lub piano. Lub suab yuav raug xa mus los ntawm tus neeg hais lus Piezo.

Kauj ruam 1: Cov ntaub ntawv

1. Arduino Uno

2. USB xaim

3. 3 daim ntawv qhia zaub mov

4.8 Pushbuttons

5. 8 100 Ohm resistors

6. "Piezo" Tus Hais Lus

7. Ntau Tus Txiv Neej Hluav Taws Xob (Txog 20)

8. Soldering Hlau

Kauj ruam 2: Tsim Kev Teeb

Tsim 8 cov nyees khawm nrog txhua tus mus rau 8 tus pin sib txawv hauv Arduino, ntxiv tus tiv thaiv rau txhua tus, thiab txuas lawv rau hauv av (siv Txiv neej cov xov hlau).

Txuas tus neeg hais lus rau tus pin Arduino, thiab lwm sab rau hauv av. Koj yuav tsum tau xaim cov xov hlau rau tus hais lus kom nws tsis poob tawm. Nco ntsoov tias ob lub xov hlau uas tau muab muag rau tus hais lus tsis txhob kov ib leeg.

Cov "#defines" no yog qhia rau tus neeg hais lus uas zaus ua rau qhov twg

cov int C = 2; cov int D = 3; cov int E = 4; cov int F = 5; const int G = 6; cov int A = 7; const int B = 8; const int C2 = 9; const int piezoPin = 10; int cState = 0; int dState = 0; int eState = 0; int fState = 0; int gState = 0; int aState = 0; int bState = 0; int c2State = 0;

Xaiv Arduino tus pin rau cov nyees khawm. "cState, dState, eState, thiab lwm yam;" yog cov hloov pauv uas txuag seb lub khawm raug nias. A 0 txhais tau tias nws tsis raug nias, a 1 txhais tau tias nws raug nias.

teeb tsa tsis muaj dab tsi () {// muab koj cov cai teeb tsa ntawm no, kom khiav ib zaug: pinMode (10, OUTPUT); Serial.begin (9600); }

void loop () {// muab koj tus lej tseem ceeb ntawm no, kom rov ua dua: cState = digitalRead (C); dState = digitalRead (D); eState = digitalRead (E); fState = digitalRead (F); gState = digitalRead (G); aState = digitalRead (A); bState = digitalRead (B); c2State = digitalRead (C2);

Lub xeev ntawm lub pob (yog tias nws tau nyem lossis tsis) raug cawm hauv "cState, dState, eState, thiab lwm yam;"

A 0 txhais tau tias nws tsis raug nias, a 1 txhais tau tias nws raug nias.

yog (cState == 1) {tone (piezoPin, 131); } lwm {noTone (piezoPin);} yog (dState == 1) {suab (piezoPin, 147); } lwm {noTone (piezoPin);} yog (eState == 1) {suab (piezoPin, 165); } lwm {noTone (piezoPin);} yog (fState == 1) {suab (piezoPin, 175); } lwm {noTone (piezoPin);} yog (gState == 1) {laus (piezoPin, 196); } lwm {noTone (piezoPin);} yog (aState == 1) {suab (piezoPin, 220); } lwm {noTone (piezoPin);} yog (bState == 1) {laus (piezoPin, 247); } lwm {noTone (piezoPin);} yog (c2State == 1) {suab (piezoPin, 262); } lwm {noTone (piezoPin);}

Yog tias lub pob nyem, nws qhia cov servo los ua cov ntawv pov thawj zaus (ceeb toom). Txoj haujlwm

{noTone (piezoPin);} qhia lawv tias yog tias lub pob tsis raug nias kom tsis ua dab tsi. Yog li thaum twg lub pob nyem, nws yuav ua nws daim ntawv teev tseg.
