Arduino基礎から確認。

最初の１３番ピンblinkから。

int led = 13;

void setup() {
// put your setup code here, to run once:
pinMode(led,OUTPUT);
}

void loop() {
// put your main code here, to run repeatedly:
digitalWrite(led,HIGH);
delay(1000);
digitalWrite(led,LOW);
delay(1000);
}

抵抗のカラーバンドの意味確認。

３色変化。

//difine
#define BLUE 3
#define GREEN 5
#define RED 6

void setup() {
// put your setup code here, to run once:
pinMode(RED,OUTPUT);
pinMode(GREEN,OUTPUT);
pinMode(BLUE,OUTPUT);
digitalWrite(RED,HIGH);
digitalWrite(GREEN,LOW);
digitalWrite(BLUE,LOW);

}

//variables
int redValue;
int greenValue;
int blueValue;

void loop() {
// put your main code here, to run repeatedly:

#define delayTime 10

redValue = 255;
greenValue = 0;
blueValue = 0;

for(int i = 0;i < 255;i += 1)
{
redValue -= 1;
greenValue += 1;
analogWrite(RED,redValue);
analogWrite(GREEN,greenValue);
delay(delayTime);
}

redValue = 0;
greenValue = 255;
blueValue = 0;

for(int i = 0;i < 255;i += 1)
{
greenValue -= 1;
blueValue += 1;
analogWrite(GREEN,greenValue);
analogWrite(BLUE,blueValue);
delay(delayTime);
}

redValue = 0;
greenValue = 0;
blueValue = 255;

}

ボタンでのコントロール。

int ledPin = 5;
int buttonOnPin = 9;
int buttonOffPin = 8;

void setup() {
// put your setup code here, to run once:
pinMode(ledPin,OUTPUT);
pinMode(buttonOnPin,INPUT_PULLUP);
pinMode(buttonOffPin,INPUT_PULLUP);
}

void loop() {
// put your main code here, to run repeatedly:
if(digitalRead(buttonOnPin)==LOW){
digitalWrite(ledPin,HIGH);
}

if(digitalRead(buttonOffPin)==LOW){
digitalWrite(ledPin,LOW);
}

}
