| [回家功課] 8顆LED燈閃爍過去 |
|
int led;
void setup() {
for(led=22; led<=29; led++){
pinMode(led, OUTPUT);
}
}
void loop() {
for(led=22; led<=29; led++){
digitalWrite(led, HIGH);
delay(500);
digitalWrite(led, LOW);
delay(500);
}
}
|
| EX01: 讓8顆LED燈閃爍回來 |
|
int led;
void setup() {
for(led=22; led<=29; led++){
pinMode(led, OUTPUT);
}
}
void loop() {
for(led=29; led>=22; led--){
digitalWrite(led, HIGH);
delay(500);
digitalWrite(led, LOW);
delay(500);
}
}
|
| EX02: 讓8顆LED燈無延遲亮回來 |
|
int led;
void setup() {
for(led=22; led<=29; led++){
pinMode(led, OUTPUT);
}
}
void loop() {
for(led=29; led>=22; led--){
digitalWrite(led, HIGH);
delay(500);
digitalWrite(led, LOW);
}
}
|
| EX03: 讓8顆LED燈無延遲亮回來，延遲改為0.1秒 |
|
int led;
void setup() {
for(led=22; led<=29; led++){
pinMode(led, OUTPUT);
}
}
void loop() {
for(led=29; led>=22; led--){
digitalWrite(led, HIGH);
delay(100);
digitalWrite(led, LOW);
}
}
|
| [回家功課] 讓LED燈漸漸變暗，必須採用--指令，延遲改為0.01秒 |
|
int led;
void setup() {
pinMode(13, OUTPUT);
}
void loop() {
for(led=255; led>=0; led--){
analogWrite(13, led);
delay(10);
}
}
