Activity 2

The IPod touch has an inbuilt mechanism called accelerometer. The device is small and it has the ability to sense the direction in which the IPhone is being held and oriented in space whether it is vertically, horizontally or sideways. The accelerator then flips the contents of the image display in the direction in which the iPod is being held in his case sideways. The accelerator then aligns the screen image sideways which is the same direction the device is being held in this case.LIS302DL accelerometer is built in iPhone and iTouch and it enables the device to know when it is slanted to its side.
