WEEK 7 

RESEARCH AND TESTING FOR THE GYRO SENSOR

On Wednesday, 7/3/2018, I had my meeting with my supervisor for further discussion on my progress work for this final year project. After receiving the gyro sensor, I manage to test it to fulfill my task from previous week. The first thing that I need to do was to solder the gyro sensor’s pin.

Soldered Gyro Sensor

After the gyro sensor’s pin has been soldered, I had done some testing on the gyro sensor to find the angle produced from the sensor. The gyro sensor were connected to the Arduino Uno and the Arduino Uno board were connected to the laptop same like the previous testing of the gyro sensor.

Connection of Gyro sensor for testing

The coding for this gyro sensor testing:

Coding For Gyro Sensor testing

The result obtained from the gyro sensor can be shown at the serial port:

Result obtained from Serial Port shows the angular velocity of the gyro sensor

From the result that obtained from the serial port, the result were then imported into excel to convert into graph result.

Imported result from the serial sensor to excel to converted into graphical result

From that graph, it can be convert into angle in degree or radian. To find the angle, it need to perform some calculation which was from angular velocity (obtained from gyro sensor) into angle in degree or radian. However, I’m still stuck in this task and still in progress. My supervisor have suggested me to do some research on the calculation that involve the gyro sensor.

This were some info that I have found from the internet:

Reference Angle

“To measure the angle using the gyro we have to integrate the signal.
But why we have to do this? 
Because the gyro give us the angular rate, so a simple way to get the angle is have the angular rate multiplied by the time [angle = angle + w * dt]”

From the information, it shows how the angle can be obtained from the gyro sensor and converted into angle in degree. However, some of the method still cannot be used in my project so I only use some of the information as my references.

From what I have done through this week, new task had been given by my supervisor, such as:

      a) Performed a calculation to find the angle in degree

      b) Made a coding to show the angle in degree produced from the gyro sensor

      c) Do the Final Year Project (FYP) Proposal

That all for this week task.
