(SKU:ELB060415)3路MOS管场效应管驱动模块 IRF540

简介

采用原装IRF540功率MOS管，可以进行PWM调节输出 可以让Arduino驱动高达24V的负载，如LED灯带、直流马达、微型水泵、电磁阀 用过PWM调可以实现LED无级调光、马达无级调速。

注意：驱动1A以上的负载需安装散热片

使用教程

样例代码1

int led1 = 9;
int led2 = 10;
int led3 = 11;

void setup() {
  pinMode(led1, OUTPUT);
  pinMode(led2, OUTPUT);
  pinMode(led3, OUTPUT);
}

void loop() {
  digitalWrite(led1, HIGH);  
  delay(1000);              
  digitalWrite(led1, LOW);
  digitalWrite(led2, HIGH); 
  delay(1000);
  digitalWrite(led2, LOW);  
  digitalWrite(led3, HIGH); 
  delay(1000);
  digitalWrite(led3, LOW);  
}

样例代码2

#define LEDR 9
#define LEDB 11
#define LEDG 10
int i = 0;

void setup() {
  pinMode(LEDG, OUTPUT);
  pinMode(LEDB, OUTPUT);
  pinMode(LEDR, OUTPUT);
}

void loop() {
  analogWrite(LEDR, 255);
  analogWrite(LEDB, 255);
  analogWrite(LEDG, 255); //off
  analogWrite(LEDR, 0);
  delay(1000);    //hong
  analogWrite(LEDG, 220);
  delay(1000);   //cheng
  analogWrite(LEDR, 0);
  analogWrite(LEDG, 120);
  delay(1000);   //huang
  analogWrite(LEDR, 255);
  analogWrite(LEDG, 0);
  delay(1000);   //lv
  analogWrite(LEDB, 0);

  analogWrite(LEDR, 0);
  analogWrite(LEDG, 255);
  delay(1000);   //zi
  analogWrite(LEDG, 0);
  delay(1000);   //bai

  analogWrite(LEDR, 255);
  analogWrite(LEDB, 255);
  analogWrite(LEDG, 255); //off

  for (i = 255; i > 0; i--) {
    analogWrite(LEDR, i);
    delay(10);
  }

    analogWrite(LEDB, i);
    delay(10);
  }
  for (i = 0; i < 255; i++) {
    analogWrite(LEDG, i);
    delay(10);
  }
  for (i = 255; i > 0; i--) {
    analogWrite(LEDR, i);
    delay(10);
  }
  analogWrite(LEDG, 0);
  analogWrite(LEDB, 0);
  analogWrite(LEDR, 0);
}
