Let's make - Pedometer

For sensor Pedometer uses ADXL345 3-axis digital accelerometer: http://www.analog.com/static/imported-files/data_sheets/ADXL345.pdf

The touchscreen displays number of steps and duration of walking. Message “no movement” is written when there is no movement. Also, the interface has START and STOP button. Algorithm samples the accelerometer data every 0.5 seconds as you walk, and dynamically adapts the threshold.
