sniffer_433_TX

/*
sketch : sniffer_433_TX       (sister of "sniffer_433_RX")
Author : Peter Matthews (CurlyWurly)   May 2017
Desc   : Copy the "int codez[]=.." line manufactured by the sister sketch "sniffer_433_RX" 
         and paste it into this sketch so that this sketch can spoof the original transmitter.
INFORMATION
************************************************************************************************ 
*** IF THE SKETCH DOESN'T SEEM TO WORK, INCREASE THE REPEAT VALUE TO 50 AND TRY AGAIN, 
*** e.g.  "int codez[] = {50........"
*** N.B. THE CORRECT REPEAT VALUE HAS TO BE VERIFIED BY YOURSELF BY TRIAL AND ERROR 
************************************************************************************************ 
N.B. Connect pin 3 (txpin) to the TX module input
  N.B. Copy the output "int codez[] = ...." from the "Sniffer_433_RX" sketch and paste where marked below
  N.B. The sniffer sketch just outputs a set value of 35 in code[0]. This means that you may have to 
       experiment using a different "repeat" value (usually a value of 15 - 45 is OK) 
  N.B. The code structure is contained from code[0] to code[n] and is defined as:
          code[0] - No. of times to repeat the code
          code[1] - No. of pulses (Hi/low combination) - This means it is half the total number of Hi and Low states 
          code[2] - Wait unit time (Hi and Low states are constructed with multiples of this) 
          code[3] - First HIGH state multiplier - multiply with code[2]   
          code[4] - First LOW  state multiplier - multiply with code[2]   
          ....
          code[n] - last LOW   state multiplier
      The     first  pulse is made up of code[3] and code[4]
      and the second pulse is made up of code[5] and code[6]
