Trying out playgrounds for the first time and I noticed something a little odd. In the first lesson when it talks about moving byte to toggle a switch it clearly said that the light turns on when the switch is ”Open” and off when “Closed”. This seems counter intuitive to the way we would normally teach electrical theory. We would use the example of a simple electrical circuit with a light. When the switch is closed the light turns on because the circuit is complete and the light receives power. When the circuit is open there is a break in the circuit and the light can not receive power. Just wonderiong if there was a specfic reason for teaching it this way in playgrounds?
