Hi everyone. I am trying to get a better understanding of the circuit in project 4. In particular, the part of the design I do not understand is the 10 kilo-ohm resistors which are plugged into the ground. I'm trying to visualize how the electricity is running through this circuit but I just don't understand those resistors. I feel very confident in my understanding of the circuits in the previous projects(where I feel I would be able to replicate the project without referencing the book), but I do not feel that way about this part of project 4.
Thanks for any help :)
