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;

}
}

加分：小蜜蜂

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);
}
