433MHz  1 Transmitter module & 4 Wireless Relay Controller for Arduiuo UNO MEGA2560

  We provide Arduiuo sample code , please contact after your order after your purchase  .        Qty:   1 PCS 433M Wireless transmitter module( Does not include Arduiuo UNO ); 4 PCS 433M  1 channels relay switch;
    Wireless transmitter module  connected with  Arduiuo uno( replace PT2262 Remote Keyfob)   USE:        Software control: How to use:send "a" trigger A channel relay,send "b" trigger A channel relay,Etc.     arduiuo core fragment( complete code please Request) :    //Author: Mr Liu //Arduiuo 1.0 //Arduiuo uno R3 //Making a wireless remote control with arduiuo    ...   //send:8 Address Bits, 4 Data Bits, Sync bit void send_data()   void setup() {   // initialize the LED pin as an output:   pinMode(ledPin, OUTPUT);     // initialize the encoder DOUT pin as an output   pinMode(data_out, OUTPUT);     Serial.begin(9600); } void loop() {   ...      while(1)   {     //get key from pc serial port     while (Serial.available() > 0)      {         keydata = Serial.read();         receive_flag = 1;         delay(2);     }         if(receive_flag == 1)//if get key,send key     {           receive_flag = 0;         if((keydata == 'a') || (keydata == 'A'))//trigger A channel relay.     {       Temporary[2] = 0xC0;// 0xC0 is A button key       digitalWrite(ledPin, HIGH);//Turn on led       send_data();//send code word        Serial.println(".....trigger A channel relay.....");     }     else if((keydata == 'b') || (keydata == 'B'))//trigger B channel relay.     {       Temporary[2] = 0x30;// 0x30 is B button key       digitalWrite(ledPin, HIGH);//Turn on led       send_data();//send code word       Serial.println(".....trigger B channel relay.....");     }      else if((keydata == 'c') || (keydata == 'C'))//trigger C channel relay.      {       Temporary[2] = 0x0C;// 0x0C is C button key       digitalWrite(ledPin, HIGH);//Turn on led       send_data();//send code word       Serial.println(".....trigger C channel relay.....");            }      else if((keydata == 'd') || (keydata == 'D'))//trigger D channel relay.      {       Temporary[2] = 0x03;// 0x03 is D button key       digitalWrite(ledPin, HIGH);//Turn on led       send_data();//send code word       Serial.println(".....trigger D channel relay.....");      }          ...      } }
