Use mbed on Nucleo-64 bits STM32f303RE ARM board with ADXL335 TRIPLE-AXIS ANALOGUE ACCELEROMETER and the Multicolour LED to design 'Fall Detection Alarm'. Use the 3 axis (X, Y, Z) accelerometer to detect fall and the three colour led to represent an alarm. Assume that when people fall, the value of acceleration is greater than 2g or less than -2g in any direction of X, Y and Z. When a fall happens, light up 3 colour leds in turn and each colour duration time is 0.2s. That is the Multicolour LED on the sensor board should change colours to green, blue and red for duration of 0.2 seconds each to detect a fall in the accelerometer.

Also, display output voltage from the potential meter.
