由于智能家居控制系统涉及到硬件和软件的配合,因此代码实现需要根据具体的硬件设备和功能需求进行定制。以下是一个简单的示例代码,用于控制智能灯光系统的开关和亮度调节功能。
```
#include <Wire.h>
#include <Adafruit_PWMServoDriver.h>
#define LED_PIN 13
#define SERVOMIN 150 // this is the 'minimum' pulse length count (out of 4096)
#define SERVOMAX 600 // this is the 'maximum' pulse length count (out of 4096)
#define USMIN 600 // this is the rounded 'minimum' microsecond length based on the minimum pulse of 150
#define USMAX 2400 // this is the rounded 'maximum' microsecond length based on the maximum pulse of 600
#define LED_OFF 0
#define LED_ON 1
Adafruit_PWMServoDriver pwm = Adafruit_PWMServoDriver();
void setup() {
pinMode(LED_PIN, OUTPUT);
pwm.begin();
pwm.setPWMFreq(60); // Analog servos run at ~60 Hz updates
}
void loop() {
int brightness = analogRead(A0); // read the potentiometer value
int ledState = digitalRead(LED_PIN); // read the LED state
// turn the LED on or off based on the button state
if (ledState == LED_OFF) {
digitalWrite(LED_PIN, LED_ON);
} else {
digitalWrite(LED_PIN, LED_OFF);
}
// set the brightness of the LED based on the potentiometer value
int pwmVal = map(brightness, 0, 1023, SERVOMIN, SERVOMAX);
pwm.setPWM(0, 0, pwmVal);
}
```
这段代码使用了Arduino开发板和PWM舵机驱动器来控制智能灯光系统。其中,通过读取模拟输入口A0的电压值来控制灯光的亮度,将亮度值映射到PWM输出的占空比上。同时,使用数字输出口13来控制灯光的开关状态。这段代码仅作为示例,实际应用中需要根据具体要求进行修改和完善。
