analogWrite()
从一个引脚输出模拟值(PWM)。可用于让LED以不同的亮度点亮或驱动电机以不同的速度旋转。analogWrite()输出结束后,该引脚将产生一个稳定的特殊占空比方波,直到下次调用analogWrite()(或在同一引脚调用digitalRead()或digitalWrite())。PWM信号的频率大约是490赫兹。
在大多数arduino板(ATmega168或ATmega328),只有引脚3,5,6,9,10和11可以实现该功能。在aduino Mega上,引脚2到13可以实现该功能。老的Arduino板(ATmega8)的只有引脚9、10、11可以使用analogWrite()。在使用analogWrite()前,你不需要调用pinMode()来设置引脚为输出引脚。
analogWrite函数与模拟引脚、analogRead函数没有直接关系。
analogWrite(pin,value)
pin:用于输入数值的引脚。
value:占空比:0(完全关闭)到255(完全打开)之间。
说明和已知问题
引脚5和6的PWM输出将高于预期的占空比(输出的数值偏高)。这是因为millis()和delay()功能,和PWM输出共享相同的内部定时器。这将导致大多时候处于低占空比状态(如:0
10),并可能导致在数值为0时,没有完全关闭引脚5和6。
通过读取电位器的阻值控制LED的亮度
int ledPin = 9;
// LED连接到数字引脚9
int analogPin = 3;
//电位器连接到模拟引脚3
int val = 0;
//定义变量存以储读值
void setup()
pinMode(ledPin,OUTPUT);
//设置引脚为输出引脚
void loop()
val = analogRead(analogPin);
//从输入引脚读取数值
analogWrite(ledPin,val / 4);
// 以val / 4的数值点亮LED(因为analogRead读取的数值从0到1023,而analogWrite输出的数值从0到255)

Kintra (: Ceann na Tràgha) is a
on the North-Western coast of the Ross of , . The settlement is within the parish of Kilfinichen and Kilvickeon. It has approximately 15 permanent residents, in addition to seasonal or recreational visitors. Most of the settlement is in the form of a line of houses parallel to the shore (a small, unpaved road, low defense wall and grassy area separate the beach from the houses).
The size of the beach is very much dependent on the : at high tide, there may be no beach and much of the grassy area is submerged. At low tide, there may be up to 50 m of beach. The bay in which Kintra resides is sheltered by numerous, small islands and outcrops composed of local
stones. Kintra lies about 2 miles north east of

代词句内指代的影响因素分析
综合语用频率统计和语言实例分析两方面的数据,我们发现,汉语代词的句内指代既不像生成语法说的那样绝对、简单,也不像认知语法说的那样琐碎、复杂。其实,影响代词指代的核心因素只有两个,即代词和参照点。代词自身的特点决定了它能指代什么、不能指代什么;参照点决定了代词在什么情况下能指代,什么情况下不能指代。虽然其他因素也会影响代词的指代,但都不是核心因素。
Abstract:
Based on the statistics of frequency and data analysis, we find that the rules of pro- noun intrasentential co-reference in Chinese neither like what generative grammar has generalized, which are nor like what cognitive grammar has generalized, which are trivial and complex. In fact, there are only two core factors which can impact pronoun intrasentential co- reference, namely pronouns and reference point. Pronoun' s characteristics determine what it can or cannot co-refer. Reference point determines that under what circumstances a pronoun can or cannot co-refer. There are also other factors that might impact the pronoun's co-reference, yet they are not the core factors.
