Homework #6 Bishop E9.1, E9.8 ,D9.2, D9.3, and the following:
C1. Write a
"temperature logger" vi that reads the temperature (using
ReadTemp.vi) and outputs the time (in seconds since the vi started)
and temperature to a file every 10 seconds. Each data point
should be on a separate line, and the time and temperature should be
separated by a "tab" character. When the vi is started, the
current time and date should be written to the file. The file
name should be entered in a file dialog box only once when the vi is
started. Load the file into Microsoft Excel and use Excel to
plot the temperature versus time.
C2. Write a vi
that parses a "command" string that has a text command
followed by three integer numbers. The numbers and command may be
separated by any number of spaces, but the command will contain no
spaces. The command string should be input on a front-panel
control. Show the command and the three numbers using indicators on
the front panel. For example, a command might be "Move 5 3
1"
C3. Write a vi
that scrambles a text message by adding a number between 1 and 10 to
the ASCII value of each character. The original text message
should be in all CAPITAL letters. The vi should have a "encode/decode" switch on the front
panel to select if the text string should be either encoded or
decoded.
Homework #7 Bishop E7.3, P7.7, D7.3, and the following:
C4 Write a vi that
displays a graph showing a red triangle inside a blue circle. The
vertices of the triangle should be on the circle.
C5
Write a vi that displays a rotating polygon with N
sides. Create a control for the rotation rate and the size of
the polygon.
C6. Write a vi that
reads the temperature and time data generated in c1 above and
displays it on a graph.
Projects
Project 1:
Using the provided "command server" and lego
bluetooth communication vis,
write a labview program that will send your
lego robot along a path. You will
need to implement commands to turn left or right and go forward and
backward. The forward and backward commands should accept
distances in inches, and the left and right commands should accept
angles in degrees. Your labview
program should have a means of calibrating the robot so that you can
obtain the most accurate results. On the last day of class, a
course will be specified and we will have a "robot
contest". The robot that completes the course and is
closest to the proper end position will win the contest.
Project 2 :
Option 1: Propose an
experiment that can be controlled by a computer. The experiment
must generate data that can be presented in a scientific paper or
presentation. In the past, students have
conducted experiments on plant photosynthesis using oxygen and CO2
sensors, as well as nonlinear dynamics experiments using a damped,
driven physical pendulum.
Option 2: Using the
reaction timer apparatus and the interface vis
provided above, conduct an experiment on human reaction time.
The apparatus is capable of generating an audio or visual stimulus
(or both), and varying the properties of the stimulus. Once the
apparatus is configured, it is commanded to "start" the
test, and when the subject pushes the button on the apparatus the
test is complete and the reaction time can be read. There
are two main types of experiments you can perform. One type of
experiment could measure the effects of a controlled parameter that
can be varied continuously over a range. For example, you may
wish to explore the dependence of reaction time on the frequency of
the sound used as the "stimulus". The other
type of experiment could test different external conditions.
For example, you may wish to determine if a person's reaction time
improves after the person has exercised for a certain amount of
time. For both types of experiments, be sure to
take enough samples to properly analyze your data. Write a LabView vi that controls the experiment and saves
the data to a file. Your data should be analyzed in Excel.
Presentation:
Create a powerpoint presentation for a 10
minute talk about your project results. The presentation should
begin with an outline and an introduction, and the data should be
presented in graphical form. The results should then be
discussed, and the presentation should end with a brief
conclusion. You will not have to actually give the
presentation.
Paper: Using this example as a guide, prepare a
paper about your experiment. Be sure to include any relevant
data tables, illustrations and graphs. Also be sure to format
your paper to duplicate the "scientific journal" format
used in the example handout.
