Arduino 433mhz

[Vizitator R3dD3vil]

Buna ziua, doresc sa realizez un termostat wireless folosind un set TX-RX in 433mhz, lcd 20x4 si senzor analogic LM35DZ, toate bune si frumoase pana adaug codul pentru transmitere in sketch, pentru transmitere folosesc libraria VIRTUALWIRE, pana acum nu am mai folosit aceasta librarie si cred ca ceva scartie in codul meu, ideea e ca fara partea de trimitere, tx, totul lucreaza ok, se afiseaza perfect  pe lcd, dupa introducere cod pentru transmitere se afiseaza asa: https://www.youtube.com/watch?v=KYcW1vQtF_8

 

 

atasez si codu sursa din sketch-ul pentru TX:

#include <EEPROM.h>#include <LiquidCrystal.h>#include <VirtualWire.h>int tempPin = A0;int led =13;float temp;float settemp;int swtu = 6;int swtd = 7;const int transmit_pin = 12;char *control;LiquidCrystal lcd(10, 11, 5, 4, 3, 2);void setup() {    pinMode (led, OUTPUT);    pinMode (tempPin, INPUT);    pinMode (swtu, INPUT);    pinMode (swtd, INPUT);    vw_setup(4000);    vw_set_tx_pin(transmit_pin);    vw_set_ptt_inverted(true);        lcd.begin(20, 4);     lcd.setCursor(0,0);     lcd.print("********************");    lcd.print("*    LOADING...    *");    lcd.print("*TERMOSTAT WIRELESS*");    lcd.print("********************");    delay(5000);    lcd.clear();    EEPROM.read (1);}void loop() {    float tvalue = analogRead(tempPin);  float mv = (tvalue/1024.0)*5000;  temp = (mv / 10);  lcd.setCursor(13,0);  lcd.print(temp);  lcd.print((char)223);  lcd.print("C");    settemp = EEPROM.read(1);  delay (250);    if (digitalRead(swtu)== 1 )  {    settemp ++;  }else{}if (digitalRead (swtd) == 1){  (settemp --); }else {}if (temp < settemp){  digitalWrite (led, 1);   lcd.setCursor (0,1);  lcd.print ("  Centrala Pornita  ");  control="1";  vw_send((uint8_t*)control, strlen(control));  vw_wait_tx();   delay(2000);}else{  digitalWrite (led,0);  lcd.setCursor (0,1);  lcd.print ("  Centrala Oprita   ");  control="0";  vw_send((uint8_t*)control, strlen(control));  vw_wait_tx();   delay(2000);}  lcd.setCursor (0,0);  lcd.print ("Set:");  lcd.print (settemp);  lcd.print((char)223);  lcd.print("C");  lcd.print("|");EEPROM.write (1,settemp);delay (250); }

Inverseaza astea doua linii:

vw_setup(4000);    vw_set_tx_pin(transmit_pin);

Arunca un ochi si pe module NRF24l01+. Foarte ieftine, raza mai mare de actiune, posibilitate de criptare, bidirectional, etc .
