With regard to your common anode bi colour LED you should have continuity as follows

Note all 3 square +9v pads have continuity with the CLR so it doesnt matter which one you use

All good!


Your 3PDT Pad numbering (shown above) is opposite what it should be. Again refer to the Guide.

That said I think you may be using the wrong LED type. We require Common Anode and not Common Cathode. It is an easy coin battery test “see image below” Only use battery under 4v.

I tested my LED and it is indeed a common anode LED as mentionned previously.

What it could be?
