Bu "Pianino" haqiqiy pianino oktavasini chalishga qodir. Tugmalarni bosish pianino tugmachasini bosishni bildiradi. Ovoz Piezo karnay orqali uzatiladi.

1 -qadam: materiallar

1. Arduino Uno

2. USB kabeli

3. 3 ta non paneli

4. 8 ta tugma

5. 8 100 Ohmli rezistorlar

6. "Piezo" spikeri

7. Ko'p erkak simlar (20 ga yaqin)

8. Lehimlash temir

2 -qadam: O'rnatishni yarating

Har birida Arduino -da 8 ta pin bor, har biriga rezistor qo'shib, ularni erga ulab (Erkak simlari yordamida) 8 tugmachani yarating.

Karnayni belgilangan Arduino piniga, boshqa tomonini esa erga ulang. Simlar karnayga lehimlanishi kerak, shunda u qulab tushmaydi. Karnayga lehimlangan ikkita sim bir -biriga tegmasligiga ishonch hosil qiling.

Bu "ta'riflar" spikerga qaysi chastotani qaysi eslatmani yozishini aytishi kerak

const int C = 2; const int D = 3; const int E = 4; const int F = 5; const int G = 6; const 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;

Tugmalarga Arduino pinlarini belgilang. "cState, dState, eState va boshqalar;" tugma bosilganligini saqlaydigan o'zgaruvchilar. A 0 bosilmasligini, 1 bosilganligini bildiradi.

void setup () {// bir marta ishga tushirish uchun sozlash kodini bu erga qo'ying: pinMode (10, OUTPUT); Serial.begin (9600); }

void loop () {// qayta ishga tushirish uchun asosiy kodingizni bu erga qo'ying: cState = digitalRead (C); dState = digitalRead (D); eState = digitalRead (E); fState = digitalRead (F); gState = digitalRead (G); aState = digitalRead (A); bState = digitalRead (B); c2State = digitalRead (C2);

Tugma holati (agar u bosilsa yoki bosilmasa) "cState, dState, eState va boshqalarda" saqlanadi;

A 0 bosilmasligini, 1 bosilganligini bildiradi.

if (cState == 1) {ohang (piezoPin, 131); } else {noTone (piezoPin);} if (dState == 1) {ohang (piezoPin, 147); } else {noTone (piezoPin);} if (eState == 1) {ohang (piezoPin, 165); } else {noTone (piezoPin);} if (fState == 1) {ohang (piezoPin, 175); } else {noTone (piezoPin);} if (gState == 1) {ohang (piezoPin, 196); } else {noTone (piezoPin);} if (aState == 1) {ohang (piezoPin, 220); } else {noTone (piezoPin);} if (bState == 1) {ohang (piezoPin, 247); } else {noTone (piezoPin);} if (c2State == 1) {ohang (piezoPin, 262); } boshqa {noTone (piezoPin);}}

Agar tugma bosilsa, u servoga sertifikat chastotasini ijro etishini aytadi (eslatma). Funktsiya

{noTone (piezoPin);} ularga hech narsa ijro etish uchun tugma bosilmasligini aytadi. Shuning uchun, tugma bosilganda, u belgilangan yozuvni ijro etadi.
