【Arduino】使用激光发射器/接收器来模拟电影里的激光报警器
本次的实验采用的是激光发射和接收两个模块，模拟电影里面的激光报警器，如果想让更好体验到报警效果可以添加一个蜂鸣器来查看效果。
本次完成的内容需要的材料：
Arduino UNO X2
Laser Transmitter module x1
Laser Receiver module x1
导线（若干）
线路图：
所需代码：
Laser send:
int lasertransmitterPin=8; //definition digital 8 pin to control the laser transmitter module
void setup()
{
pinMode(lasertransmitterPin,OUTPUT); //Set the digital 8 port mode, OUTPUT: Output mode
}
void loop()
{
digitalWrite(lasertransmitterPin,HIGH); //HIGH is set to about 5V PIN8
// delay(5000); //Set the delay time, 5000 = 5S
//digitalWrite(lasertransmitterPin,LOW); //LOW is set to PIN8
// delay(5000); //Set the delay time, 5000 = 5S
}
Laser recv:int laserreceiverPin=8; //Set the digital 8 to the S pin
int LED=13;
void setup() {
pinMode( LED,OUTPUT);//initialize the S pin as input
pinMode( laserreceiverPin,INPUT);//initialize the S pin as input
Serial.begin(115200 ); //opens serial port, sets data rate to 9600 bps
}
void loop() {
if(digitalRead(laserreceiverPin)==LOW){
digitalWrite(LED,HIGH);
Serial.println("No laser received"); //send data to the serial monitor
}else{
Serial.println("Received laser"); //send data to the serial monitor
digitalWrite(LED,LOW);
}
delay(500); //delay 0.2s
}
