esp8266控制Arduinol led燈亮滅的程序，想加一個紅外感應功能

會編Arduino的請看看
上面是手機通過esp8266控制Arduinol  led燈亮滅的程序，想在這個基礎(chǔ)上加一個紅外感應的，人靠近，燈亮，人離開，燈滅，請問應該怎么加，試了好幾種方法，都不行int LED = 9;int Sensor = 7;
char ch[10];
void setup()
{
  pinMode(LED,OUTPUT);
  pinMode(Sensor,INPUT);

  Serial.begin(115200);
}
void loop()
{
  if(Serial.available())
  {
  for(int i=0;i<9;i++)
  {
ch[i]=char(Serial.read());
delay(1);
  }
  if(strncmp(ch,"1",1)==0)
  {
digitalWrite(LED,HIGH);
  Serial.println("1");
  }
else if(strncmp(ch,"2",1)==0)
{
  digitalWrite(LED,LOW);
  Serial.println("2");
  }
  }

---------------只方便作延時熄燈-------------

#include <TimerOne.h>
#define TIMER_US 100000 // 100mS set timer duration in microseconds
#define TICK_COUNTS 200 // 20S worth of timer ticks

volatile long tick_count = TICK_COUNTS;       // Counter for 20S

void setup(){
pinMode(13, OUTPUT);
attachInterrupt(0, blink, FALLING);
// LOW to trigger the interrupt whenever the pin is low,
// CHANGE to trigger the interrupt whenever the pin changes value
// RISING to trigger when the pin goes from low to high,
// FALLING for when the pin goes from high to low.

//Board       int.0 int.1
//Uno, Ethernet 2    3

Timer1.initialize(TIMER_US);                // Initialise timer 1
Timer1.attachInterrupt( timerIsr );          // attach the ISR routine h
}

void loop(){
//Add your task
}

void blink(){
digitalWrite(13, HIGH); // Toggle pin 13 HIGH
tick_count = TICK_COUNTS; // Reload
timer1.restart();
}

// --------------------------
// timerIsr() 100 milli second interrupt ISR()
// Called every time the hardware timer 1 times out.
// --------------------------
void timerIsr(){
if (!(--tick_count)){ // Count to 20S
timer1.stop();
digitalWrite(13, LOW); // Toggle pin 13 LOW
}
}

Timer1要改成這樣的
。。~~~~~~
