(二)、PWM调光 代码 intpotpin =0;intledpin =11;intval =0;voidsetup() {//put your setup code here, to run once:pinMode(ledpin, OUTPUT); Serial.begin(9600); }voidloop() {//put your main code here, to run repeatedly:val =analogRead(potpin); Serial.println(val); analogWrite(ledpin...
01 模拟输出 analogWrite(pin, value) pin: 选定的引脚号码 value:取值范围 0-255 之间的PWM频率值, 0对应off, 255对应on 没有返回值 所以我认为是8位的DA转换 02 模拟输入 analogRead(pin) 返回值 0到1023之间的值 所以我认为是10位的AD转换 03 代码 //引脚3连接LEDintledPin =9;//变量val用来存储模拟...
方法2:手动PWM *** void setup() { pinMode(13, OUTPUT); } void loop() { digitalWrite(13, HIGH); delayMicroseconds(100); // Approximately 10% duty cycle @ 1KHz digitalWrite(13, LOW); delayMicroseconds(1000 - 100); } *** 手动PWM的优势:可以使用任何数字...
voidsetup(){pinMode(A4,OUTPUT);}voidloop(){digitalWrite(A4,HIGH);} 然后这样就能完成一个最基本的点灯步骤了。 2.3.3 delay(s) 延时函数 s 的单位为 毫秒,我们可以直接在 loop() 函数中,使用 delay() 函数,并且 配置灯泡的亮灭,就可以实现一些好玩的流水灯效果啦 ...

int outputValue = 0; // value output to the PWM (analog out) void setup() { // initialize serial communications at 9600 bps: Serial.begin(9600); } void loop() { // read the analog in value: sensorValue = analogRead(analogInPin); ...
using, be sure to use another PWM capable pin. On most Arduino, the PWM pins are identified with a "~" sign, like ~3, ~5, ~6, ~9, ~10 and ~11. This example code is in the public domain. https://www.arduino.cc/en/Tutorial/BuiltInExamples/Fade ...
