Q7. Tilt it up on its longer edge, with the servo ports up. (As in Figure 3-14a).
Q8. Place it flat on a table.
Q9. The degree splits a circle into 360 units, whereas a binary radian splits a circle
Q10. 0 to 255. They represent the angle, in brads (binary radians).
Q11. Degrees = brads * 360 / 256.
Q12. -127 to +127, which represents the opposite and adjacent sides of the triangle.
