+# making a balance bord
+
+Since We are not able to connect the wii fit bord we have to come up with a solution. We thought of it for some time and what we want to do with it. Origanlly we wanted to use the balance bord for excersises such as standing on one leg. This is a simple leg excersise we wanted to have. We thaugt of multiple solutions to still have this excersise. However we still needed to think of a design for the frame.

+# the frame
+
+We wanted it to have a similar style to the balance bord. howevere since we can make or own we wanted to make it a bit taller. This makes it easier to implement some other excersise such as the step up. This is na excersise that benefits from a taller box than the wii fit box.

+We can use a LDR to determine if someone is standing on the bord
