/*This arduino controls orientation...it is always on standby and is only activated by the master arduino
   immedietly the rocket starts to free fall.the function of this is to make sure the
   rocket is always on the right way up for effective landing.This is also resposible for deploying the parachute
   THIS SYSTEM IS ON THE I2C BUS HENCE IS A SLAVE
   Depending on the fall acceleration the microcontroller can trigger master to fire to reduce speed
  Has a unique adress to identify it from all other devices on the bus
   Need to bring altitude sensor to this side

   immedietly the rocket fires.the function of this is to make sure the
   rocket is always on the right way up for takeoff.
   THIS SYSTEM IS ON THE I2C BUS HENCE IS A SLAVE
 * *Has a unique adress to identify it from all other devices on the bus
however this system is not a must since its function is too regulate it to 
vertical flight...this is only for best precision...
more attention is to be given to the landing system.......
