How to read schematics

I think a little tutorial on how to build the project circuits Please text me the parts your child needs, and I'll send them to school. Thanks.

Yo... What sensors did you use for your chessboard? We all know you said a "clone" of Omron's TL-W5MC1 but no one knows where you got them from. Could you please explain where you got them from or what the sensors are called that you ordered so we can use those too?
