I have a starter kit from Mouser bought Jan'13. I'm on Project 5, and...
1) The base of the potentiometer is too wide to fit as per the book diagram. It stretches 5 holes across, in the book the diagram shows it as 2. I cannot make the circuit in the book. also 2) The header short end is too short to fit into the servo female end.
Now, I've fixed (2) by using short leads instead, which as a bodgejob looks like it'll work. But I'm wondering how to tackle 1 at the moment, trying to redo the diagram.
This, and all the other QC issues like the wires being the wrong colours in the book (or in the kit?) really isn't helpful. There are QC issues with the kit that need to be addressed.
