Just realised while using the Morse function in another project that it only handles lower case letters!
Sorry for the delay, I have been away from my computer for a while.
The wiring is quite simple you take the +VE from the dc piezo buzzer (these are the ones with an in built driver circuit) to Arduino PWM pin 11 and connect the ground of the buzzer to the ground pin of the Arduino. So just 2 wires to connect.
Thank you for the additional information.
I came to Arduino via software not software via Arduino so my knowledge of how the pins work internally can be a bit sketchy.
