## 程式一:用滑動式電位計控制LED亮度
```cpp
#define LED 11
#define pot A5
void setup() {
pinMode(LED, OUTPUT);
digitalWrite(LED, 1);
Serial.begin(9600);
}
void loop() {
int i = analogRead(pot);
int j = map(i, 0, 1023, 0, 30);
analogWrite(LED, 255-j);
Serial.print("pot讀的數值=");
Serial.print(i);
Serial.print(" LED顯示的亮度數值=");
Serial.println(j);
delay(200);
}
```
# 06_109/04/21
## 程式一:Serial視窗輸入0~9控制LED亮度
```
說明：
Serial視窗輸入0~9控制LED亮度，其中0為最暗，9為最亮
Serial輸入格式如下:
假設輸入為：'1' Serial視窗輸出為：
鍵盤輸入的是:『1』
亮度等級為：『1』
```
```cpp=
#define LED 11
void ShowLED(int);
int in = 0;
void setup()
{
pinMode(LED, OUTPUT);
digitalWrite(LED, 1);
Serial.begin(9600);
}
void loop()
{
if (Serial.available() > 0)
{
in = Serial.read();
Serial.print("鍵盤輸入的是:『 ");
Serial.print(in - 48);
Serial.println("』");
in = in - '0';
if (in >= 0 && in <= 9 )
{
ShowLED(in);
}
}
}
void ShowLED(int level)
{
int i = map(level, 0, 9, 255, 0);
Serial.print("亮度等級為=『");
Serial.print(level);
Serial.println("』");
analogWrite(LED, i);
}
```
## 程式二:
```
功能:判斷Serial輸入幾個字元，根據輸入1~2個字元回饋字元數
ex.
輸入"72"+"enter" 輸出視窗會顯示:"現在輸入2個字元"
輸入"5"+"enter" 輸出視窗會顯示:"現在輸入1個字元"
```
```cpp
#define LED 11
char recData[6] = {0, 0, 0, 0, 0, 0};
int i = 0 , recN = 0;
void setup()
{
pinMode(LED, OUTPUT);
digitalWrite(LED, 1);
Serial.begin(9600);
}
void loop()
{
if (Serial.available() > 0)
{
CLR_recData();
recN = Serial.readBytesUntil(13, recData, 6);
if (recN == 1)
{
Serial.println("現在輸入一個字元");
}
if (recN == 2)
{
Serial.println("現在輸入兩個字元");
}
}
}
void CLR_recData()
{
for (int i = 0; i < 6; i++)
recData[i] = 0;
}
```
# 07-109/4/28
## 程式一:
```
功能:Serial輸入數字和利用u.d調整亮度，並回饋
ex.輸入:87
輸出:
LED亮度等級為『87』
再輸入:U
輸出:
目前輸入的key為『U』
LED亮度等級為『97』
```
```cpp
