Arduino "toCharArray()" problem code

hello,

I'm trying to build an Arduino project that according to a string that fed into the system via Bluetooth

module (HC 05) to divide the string to a char array and display every char for 2 sec on a 7 segment which

connected at PORT D.

I didn't succeed in writing the code.

I would be more than happy is anybody will help me or just write the code (I think that is shouldn't be a

long or uneasy to write)

THANK YOU.

Bar toplian.

I tried to read my serial data into a char array but I cannot really make it
I don't know what to write that put my serial data into a char array variable.

Maybe serial input basics can be a start.
