[51] how to send number using ht12e and receive using ht12d

[MANO.5]

Hai
my project was measuring vehicle speed using gps module and send that value to nearest controller using ht12e and receive using ht12d.encoder has 4 input data pins.so i decide to split the 4 digit and send each digit seperately.But in receiver side i don't know how to receive and made as original data???

you can do something like this,

On transmitter side,

   // your speed measurement code here
    disp_value = vehicle_speed;

// split the value and send it 
      digits[0] = (disp_value/1000)%10;   // extract thousand's
      digits[1] = (disp_value/100)%10;    // extract hundreds
      digits[2] = (disp_value/10)%10;     // extract tens
      digits[3] = (disp_value%10);         // extract ones

On receiver side,
// get the value and store it in a array

disp_value = (digits[0] * 1000) + (digits[1] * 100) + (digits[2] * 10) + (digits[3]); 
         vehicle_speed = disp_value;
         // do something

Hope it helps.

yes but this digit should contain nibble values only.
