Multiple Transmitter

[tmsak]

i want to transmit the data not in all three at a time

• 1 if i'm in under the 1st transmitter the data should only transmit in 1
• 2 if i'm in under the 2nd transmitter the data should only transmit in 2
  i'm declaring like this
  ///
  #define OUT_LED0() DDRD = ((1 << 2))
  #define OUT_LED1() DDRD = ((1 << 3))
  #define OUT_LED2() DDRD = ((1 << 4))
  ////
  IN void setup()
  {
  OUT_LED0() DDRD = ((1 << 2))/// if i declare like this all three will start to transmit

OUT_LED1() DDRD = ((1 << 3))

OUT_LED2() DDRD = ((1 << 4))

So any one can help me in this.....
