Hjälp med program till arduino (C)
Jag behöver lite hjälp, jag håller på och bygger ett alarm med hjälp av en arduino uno, GSM-modul, RFID-läsare samt ett piezo-element. Tanken är att Arduinon ska startas när dörren öppnas (den strömsätts då), den ska börja köra igång gsm-skölden och sen läsa av ifall det finns ett RFID-kort framför läsaren, och om det finns ett sådant så ska den spela upp ett ljud och sen stänga av gsm-modulen och inte göra någonting mer. Om det inte presenteras ett RFID-kort ska den ringa upp ett nummer.
Jag har lyckats få min arduino att spela upp ljud, att läsa av RFID-kort samt att ringa upp mitt nummer med individuella program, men inte lyckats få det att samspela som jag vill. Såhär ser programmet ut:
const int gsmPin = 7; // the number of the gsm pin
int gsmState = HIGH; // gsmState used to set the GSM
int gsmOff = LOW;
#include <SoftwareSerial.h> //Library for the GSM-module
#include <SPI.h> //Library for RFID-reader
#include <MFRC522.h> //Library for the RFID-reader
#include <pitches.h> //Library for the piezo
#define SS_PIN 10 //SS-pin for the RFID-reader (SDA)
#define RST_PIN 9 //RST pin for the RFID-reader
MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance.
SoftwareSerial Sim900Serial(2, 3);
void setup()
{
SPI.begin(); // Init SPI bus
mfrc522.PCD_Init(); // Init MFRC522 card
pinMode(gsmPin, OUTPUT);
digitalWrite(gsmPin, gsmState);
delay(20000);
Sim900Serial.begin(115200); // the GPRS baud rate
delay(2000);
Sim900Serial.println("AT+IPR=19200"); // Set the baud rate
delay(500);
Sim900Serial.begin(19200); // the GPRS baud rate
delay(1000);
}
int ljud = NOTE_C4;
void loop()
{
if ( mfrc522.PICC_IsNewCardPresent()){
delay(2000);
tone(8, ljud);
delay(2000);
noTone(8);
digitalWrite(gsmPin, gsmOff);
while(1);
}
else
Sim900Serial.println("ATD+46xxxxxxxx;");//'*'instead the phone number you want to dial
delay(100);
Sim900Serial.println();
delay(20000);
Sim900Serial.println("ATH");
while(1);
}
Det som händer för tillfället är att den ringer upp mitt nummer och sen lägger på, även fast jag har kortet framför läsaren. Någon som vet vad som kan vara fel?
Dessa övriga 3 program fungerar (gör det de ska)
const int gsmPin = 7; // the number of the gsm pin
// Variables will change:
int gsmState = HIGH; // gsmState used to set the GSM
// set the digital pin as output:
/*Note:This code is used for Arduino 1.0 or later*/
#include <SoftwareSerial.h>
SoftwareSerial Sim900Serial(2, 3);
void setup()
{
pinMode(gsmPin, OUTPUT);
digitalWrite(gsmPin, gsmState);
delay(30000);
Sim900Serial.begin(115200); // the GPRS baud rate
delay(2000);
Sim900Serial.println("AT+IPR=19200"); // Set the baud rate
delay(500);
Sim900Serial.begin(19200); // the GPRS baud rate
delay(1000);
}
void loop()
{
Sim900Serial.println("ATD+46xxxxxxx;");//'*'instead the phone number you want to dial
delay(100);
Sim900Serial.println();
delay(20000);
Sim900Serial.println("ATH");
while(1);
}
