以下是Arduino上使用TCS3200色标传感器的示例代码:
```c
const int S0 = 4;
const int S1 = 5;
const int S2 = 6;
const int S3 = 7;
const int OUT = 8;
int frequency = 0;
void setup()
{
pinMode(S0, OUTPUT);
pinMode(S1, OUTPUT);
pinMode(S2, OUTPUT);
pinMode(S3, OUTPUT);
pinMode(OUT, INPUT);
Serial.begin(9600);
}
void loop()
{
digitalWrite(S2, LOW);
digitalWrite(S3, LOW);
frequency = pulseIn(OUT, LOW);
Serial.print("Red: ");
Serial.println(frequency);
digitalWrite(S2, HIGH);
digitalWrite(S3, HIGH);
frequency = pulseIn(OUT, LOW);
Serial.print("Green: ");
Serial.println(frequency);
digitalWrite(S2, LOW);
digitalWrite(S3, HIGH);
frequency = pulseIn(OUT, LOW);
Serial.print("Blue: ");
Serial.println(frequency);
delay(500);
}
```
这段代码使用了4个数字引脚来控制传感器的输出频率,并通过pulseIn()函数读取输出。其中,S2和S3引脚用于选择输出频率,OUT引脚读取传感器的输出。在循环中,代码分别读取红、绿、蓝三个颜色通道的输出,并将其打印到串口监视器中。
