hey,
i receive one value from an accelerometer that shows the roll of the accelerometer the value ranges from-180 to 180 which is 360 degree angel.
what i want is to represent this value on the screen by drawing a line that would rotate accordingly to my accelerometer.
this video should give you an idea of what im trying to achieve
