/*Analog input, analog output, serial outputReads an analog input pin, maps the result to a range from 0 to 255 and usesthe result to set the pulse width modulation (PWM) of an output pin.Also prints the results to the Serial Monitor.The circuit:- potentiometer connected to analog pin ...
最后未处理值和已换算值都发送到Arduino IDE软件的串口监视窗口里。 // These constants won't change. They're used to give names to the pins used:constintanalogInPin=A0;// Analog input pin that the potentiometer is attached toconstintanalogOutPin=9;// Analog output pin that the LED is attach...

ADC0-ADC5 其实是作为 PC0-PC5 的第二功能存在的,分别对应 Arduino 定义 A0-A5。也正因为次,在 Arduino 的官方指南中提到,“The analog input pins can be used as digital pins, referred to as A0, A1, etc. ”。说的是,模拟输入口可以当数字口一样用。对于A0-A5来说,确实不错。但对于第一功能就...
将指定的引脚配置成输出或输入。详情请见digitalpins。 语法: pin Mode(pin, mode) 参数: pin:要设置模式的引脚 mode:INPUT或OUTPUT 返回 无 例子: led Pin=13//LED连接到数字脚13 voidsetup() { pin Mode(led Pin, OUTPUT) ;//设置数字脚为输出 } voidloop() { digital Write(ledPin, HIGH) ;//点...

模拟输出 Analog output analogWrite(pin, value) 在已有的引脚上使能软件PWM功能。PWM可以用在引脚0~16。调用analogWrite(pin, 0) 可以关闭引脚PWM。取值范围:0~ PWMRANGE,默认为1023。 PWM 范围可以使用analogWriteRange(new_range)语句来更改。 PWM 默认频率:1KHz。使用analogWriteFreq(new_frequency) 可以更改频率...
