We decided to do a combination of things to make up the switch. One being that there are connections on either end of the book and a photo-resistor working in tandem. The general idea is that when the book closes then the wires meet and that allows the circuit to be finished. Then all you need is some light to shine right at the photo-resistor to turn on the green LED. The general idea is that maybe you want your kid to be reading right now so when the light is on that means the book isn’t open and being read so the kid isn’t reading. Maybe the kid needs to use a lamp to read cause it’s night time and can’t read the book without the lamp’s light incorporating the light part. Honestly there are a lot of ways to think about its use but it’s a weird switch for sure.
