Laser Tag semi automatic IR ability

again can master me concept of adding semi auto firing program.

  }
}

look in code @ line

code: [select]

// compare triggerstate previous state
  if (triggerstate != lasttriggerstate) {
...
} else

that's makes wait trigger release. need define want yo if come during next loop thee triggerstate being firing
