【DFRobot Bluno试用体验】光敏电阻控制LED

准备工具：电脑；DFRobot Bluno开发板;面包板；光敏电阻；10K电阻；USB线一根;杜邦线

                若干

光敏电阻部分原理图：

硬件连接图（在这我用了云智易开发板上的光敏电阻模块）：

程序代码：

// the setup routine runs once when you press reset:

void setup() {

  // initialize digital pin 13 as an output.

  pinMode(13, OUTPUT);

}



// the loop routine runs over and over again forever:

void loop() {

  // read the input on analog pin 0:

  int sensorValue = analogRead(A0);

  if(sensorValue>250){

  digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)

 }else{

  digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW

 }

}
