Power and Light

So, 3 batteries or 4? The neopixels specify 6V max, so 4xAA is a bit risky. Nominally AA cells are 1.5V, but new ones can be a little more. To be safe I used 3, and added a wire where the 4th battery would go. Multimeter says 4.8V. Perfect.

You can see also where I have attached leads to a light sensor. I put heat shrink over the joins. I can't test it yet as I am still waiting for my resistors in Delivery 2.

Connect the battery box to an EtherTen pre-loaded with the blink sketch, and flip the switch. Perfect!

I can't wait for the rest of the parts.
