Hola, estoy intentando emitir y recibir usando solo un arduino, pero si esta escuchando no envía y viceversa. Necesito que mande un código de 4 dígitos cuando un sensor PIR detecta presencia y que también pueda recibir códigos de 4 dígitos a la vez, ¿es posible?
El código que tengo para detectar presencia y enviarla es el siguiente:
#include <RCSwitch.h>
RCSwitch mySwitch = RCSwitch();
int calibrationTime = 30;
//the time when the sensor outputs a low impulse
long unsigned int lowIn;
long unsigned int pause = 5000;
boolean lockLow = true;
boolean takeLowTime;
int pirPin = 7; //the digital pin connected to the PIR sensor's output
int ledPin = 8;
int rele = 0;
void setup()
{
Serial.begin(9600);
pinMode(pirPin, INPUT);
pinMode(ledPin, OUTPUT);
pinMode(rele, OUTPUT);
digitalWrite(pirPin, LOW);
//give the sensor some time to calibrate
Serial.print("calibrating sensor ");
for(int i = 0; i < calibrationTime; i++)
{
Serial.print(".");
delay(1000);
}
Serial.println(" done");
Serial.println("SENSOR ACTIVE");
delay(50);
mySwitch.enableTransmit(10);
}
void loop(){
if(digitalRead(pirPin) == HIGH)
{
mySwitch.send(5393, 24);
digitalWrite(ledPin, HIGH); //the led visualizes the sensors output pin state
digitalWrite(rele, HIGH);
if(lockLow)
{
//makes sure we wait for a transition to LOW before any further output is made:
lockLow = false;
Serial.println("---");
Serial.print("motion detected at ");
Serial.print(millis()/1000);
Serial.println(" sec");
delay(50);
}
takeLowTime = true;
}
if(digitalRead(pirPin) == LOW)
{
mySwitch.send(5396, 24);
digitalWrite(ledPin, LOW); //the led visualizes the sensors output pin state
digitalWrite(rele, LOW);
if(takeLowTime)
{
lowIn = millis(); //save the time of the transition from high to LOW
takeLowTime = false; //make sure this is only done at the start of a LOW phase
}
//if the sensor is low for more than the given pause,
//we assume that no more motion is going to happen
if(!lockLow && millis() - lowIn > pause)
{
//makes sure this block of code is only executed again after
//a new motion sequence has been detected
lockLow = true;
Serial.print("motion ended at "); //output
Serial.print((millis() - pause)/1000);
Serial.println(" sec");
delay(50);
}
}
}
Gracias.
