Week 3

During the lab session :

Figure 1: The lowest voltage during inactive movement

Figure 2: Activity during the sensor sense

Figure 3: The graph show the sensor sense movement and no movement 

Figure 4: The whole circuit to test the sensor

Figure 5: The accelerometer sensor

Figure 6: LED to test the result from sensor

Figure 7: The sensor and LED

Figure 8: The programming 

During the lab session, I was test the function of the sensor. In this lab, I test the X axis to check whether it can detect movement or not. The sensor was function well and very accurate. The LED used to indicate the movement of the sensor) mean it detect movement). In X orientation, The MSB of the LED show the highest  or most activity and the LSB of LED show the lowest of activity of the sensor. 

This video show how the sensor detect X axis ( X-axis is upward and downward)

During the highest peak, the sensor is at high level and during the lowest peak ( refer the video), it show the sensor is at lower level.
