My mistake. It seems the switch connects with all legs going live when pressed, not side by side individual switches.
Other comments remain
I was wondering if it was me or or just inexperience ?
But the momentary switches on my starter kit (Purchased Dec 2020) seem to be 90 degs different to the diagrams and DO NOT fit over the centre bar as shown in the project diagrams. so wiring is a bit of a headache.
I have seen other problems reported on "wobbly pots" and being to big to fit as described in the diagram.
It seems that the colouring coding of the resistors in the project book are shown back to front.
I expected more from a quality starter kit and now beginning to worry that, if I follow the project instructions, I may end up frying my board.
