corrected for slow rs232 output from arduino
Aug 27 - added ping sensor with LED visual aid.
6:30pm added fire laser attached to interrupt
Aug 28 2016 - added DHT11 temp sensor and led visual aid. added OLed - using timeAction
9/1 Changed FireLaser from interrupt to timedAction after re-reading some of my notes on interrupts causing millis to stop counting while activated.
Changed LedPin to analogWrite, modified RS232 to display less information
