Sketch won't run

When I put Serial.begin () under void setup(void)

I got this error
exit status 1
no matching function for call to 'HardwareSerial::begin()'

So where should I put it. Actually I did ask for you to point me to where I should put Serial.begin in another post

Put it in setup(), but you must specify the baud rate.

When I asked what baud rate you had used in the Serial.begin() you said, in post #10

It was 57600 as specified in the said sketch

So as before I uploaded the Parola_Scrolling sketch and it returned the exact same in a Serial Monitor as it did before.

The display lights up, but does not show anything at all in the display.

I have solved the problem now, in that I am now powering the Arduino by a 9volt power supply, and the display is now working fine. The text and numbers are scrolling across the the display.

I finally realised that 5volts was never going to be enough, as there are 3 devices connected to the breadboard, which all are 5 volt devices.

Thanks
