Sensor Challenge: 1 getting an accurate answer

You will need a compass or some way to know what direction is were

The point of this challenge is I want you to program your robot so that it will spin in a circle than stop for a half a sec beep, well your robot is stopped I want you to make a note of what direction the sensor is pointing when it stoped and then the robot should repeat this without you touching the robot .

Run this 20 at least times

It needs to be accurate to at least 5 degrees.

Needs to be moving at a speed that realistic for what you want the robot to do
