The diagrams are correct. It's come to my attention that some Nano boards have their analog pins switched. Did you purchase your own Nano or use one from the Chippernut store? Take a look at the pinout on these boards. https://www.chippernut.com/store/p7/Nano_328P.html All Nano boards and components from the Chippernut store are tested to make sure they work correctly on the shiftlight code prior to shipment. Please let me know if you received one from me that isn't working. you may email me directly at jon@chippernut.com In either case, if the analog pins on your Nano are swapped, it's simple programming change to reassign the correct values. Sorry for any hassle this has caused.

V2.X of the Nano boards have the Analog pins going in the opposite direction. V3.0 Nano is the model you want. See this post:
