好的,以下是Arduino电位器控制舵机然后光敏电阻控制灯带的代码示例。请将舵机和光敏电阻连接到Arduino的相应引脚,然后上传以下代码:
```
#include <Servo.h>
Servo myservo; // create servo object to control a servo
int potpin = 0; // analog pin used to connect the potentiometer
int val; // variable to read the value from the potentiometer
int ledPin = 9; // LED connected to digital pin 9
int lightVal; // variable to read the value from the light-dependent resistor
void setup() {
myservo.attach(3); // attaches the servo on pin 3 to the servo object
pinMode(ledPin, OUTPUT); // set the LED pin as an output
Serial.begin(9600); // initialize serial communication at 9600 bits per second
}
void loop() {
val = analogRead(potpin); // read the value from the potentiometer
val = map(val, 0, 1023, 0, 179); // scale the value to servo angle range
myservo.write(val); // set the servo position based on the scaled value
delay(15);
lightVal = analogRead(A0); // read the value from the light-dependent resistor
if (lightVal < 400) { // if the light is dim
digitalWrite(ledPin, HIGH); // turn on the LED
} else { // if the light is bright
digitalWrite(ledPin, LOW); // turn off the LED
}
Serial.println(lightVal); // print the light value to the serial monitor
delay(500); // wait for half a second
}
```
这段代码会从电位器读取模拟值,并将其映射到舵机的角度范围内。然后,代码会从光敏电阻读取模拟值,并根据光线的强度控制LED灯带的亮度。在代码中,我将LED连接到数字引脚9,您可以根据需要更改此引脚。
