Hi guys, Whilst I wait for the sockets to arrive I thought I might experiment with putting sound on. The connections seem simple enough but my attempts doesn't work!
I've followed the instructions which says to use the user port. Connect the GND to the N and the 'live' to the speaker via a 50-500k resistor at M. Admittedly I have only used a 10k resistor but I expected this just to be loud - but maybe it's this that's causing no sound!
Schematic is here:

A B C D E F H J K L M N
I've also seen this:
CB2 (the 2nd to last pin on USER port) -----> 20 ohm resistor ------> (+) PIEZO BUZZER (-) ---------> GROUND (last pin on the USER port)
Which is what I've done though not the same resistor.
Any advice?
Best wishes,
John
