I am disappointed in this item. The instructions were poor particularly in the parts description . I am an electronics engineer with a lifetime's experience and no way can I get it to work. The on/off switch for starters was O/C and it was a mystery as to which way round the leds went . Not happy.

  • Bernie In the instructions there's an arrow pointing at the switch to show that one side is intended, and that's the side that goes to the outside of the PCB. I was having trouble with the resistors until I gave up on Ohms and just followed the colour coding as per the photos in the instructions. But really, they should tell you which is which (IMO).
