Hello MAKER UNO!

寫腳： digitalWrite(pin, 輸出);
pin：要寫的腳位
輸出：HIGH, LOW

void setup() {   pinMode(13, OUTPUT);   digitalWrite(13,HIGH); } void loop() {  }

LED輪流亮

void setup() {   for (int i=2; i<=13; i++) {     pinMode(i, OUTPUT);   }   digitalWrite(13,0); } int digit[] = {0,0,0,0,0,0,0,0,0,0,0,0,0,0}; int i=0; void loop() {   for (int i=2; i<=13; i++) {     digitalWrite(i,digit[i]);     delay(100);     if (digit[i]==0) digit[i]=1;     else digit[i]=0;       } }

int sheet[]={0,261,294,329,349,392,440,493,523}; #define BUTTON 2 #define BUZZER 8 int melody[] = {   5,3,3,0,4,2,2,0,1,2,3,4,5,5,5,0 }; int noteDurations[] = {   10, 10, 10, 10, 10, 10, 10, 10, 10,10, 10, 10, 10, 10, 10, 10 }; int pin; int ledArrayHigh; int ledArrayLow; boolean mode = false; boolean buttonPressed = false; void setup() {   delay(1000);     pinMode(BUTTON, INPUT_PULLUP);   for (pin = 3; pin < 14; pin++) {     pinMode(pin, OUTPUT);   }   for (int thisNote = 0; thisNote < 16; thisNote++) {     int noteDuration = 1000 / noteDurations[thisNote];     tone(BUZZER, sheet[melody[thisNote]], noteDuration);     int pauseBetweenNotes = noteDuration * 1.30;     delay(pauseBetweenNotes);     noTone(BUZZER);   } }

按鈕～

pinMode(pin, 模式);

模式：

pullup 預設要拉高

再使用 digitalRead(2) 讀取數值

digitalRead(2) void setup() {   for (int i=3; i<=13; i++) {     pinMode(i, OUTPUT);     digitalWrite(i, HIGH);   }   pinMode(2, INPUT_PULLUP); } bool sw=false; void loop() {   if (digitalRead(2)==HIGH) sw=HIGH;   else sw=LOW;     for (int i=3; i<=13; i++) {       digitalWrite(i, sw);   } }

寫Serial

Arduino

int f[]={0,261,294,329,349,392,440,493,523}; void setup() {   pinMode(8,OUTPUT);   Serial.begin(9600); } void loop() {   if (Serial.available()) {     char now = Serial.read();     Serial.println(now);     if (now=='1') tone(8,f[1], 300);     if (now=='2') tone(8,f[2], 300);     if (now=='3') tone(8,f[3], 300);     if (now=='4') tone(8,f[4], 300);     if (now=='5') tone(8,f[5], 300);       }   }

Processing

先匯入 

import processing.serial.*;

宣告

Serial myPort;

指定port

myPort = new Serial(this, "/dev/cu.usbserial-14220",9600); 

寫入

myPort.write(key);

完整Code

import processing.serial.*; Serial myPort; void setup() {   printArray(Serial.list());   myPort = new Serial(this, "/dev/cu.usbserial-14220",9600);  } void draw() {   } void keyPressed() {     myPort.write(key); }
