Now that the code is set for Serial Port reading and writing, implement the following into your code. 

When the value ‘1’ is entered into the Serial Monitor, send the string “Number 1 received” 

When the value ‘2’ is entered into the Serial Monitor, send the string “Number 2 received” 

Code is to loop, displaying the message every 1 second.  */
