Yes i am using the serial terminal option in proteus...
serialEvent() is an interrupt code means that it supposed to be called when data is available on serial port...
first while statement is because i don' t want my arduino to do anything till all data comes in...
and second its just that i hav code to write below but wanted to see whether the code is actually receiving the proper data that i have sent.....that's it...
its just the piece of code in my project but i am stuck with this....
and tried Serial1.read() ....its showing error during compilation...'Serial1' was not declared in this scope...
