AWHS Principles of Technology

Woodworkers are the bloggers today.

goals:

programmers – test your code with a momentary switch, alligator clips and the 3d printed trigger switch.

CAD/CAM – meet with Mr. Milstead about your 3d printed trigger switch.  What works?  What doesn’t? Work with the programmer to make changes for your trigger switch.

blog post: 

woodworking – images of completed box and/or plasma cut backplate.  If you begin working on the golf course layout then include pictures of your progress.  Write about what you accomplished and what you will do on Thursday.

CAD/CAM – if you made changes to your design, what are those changes?  What are your plans for Thursday? How did your 3d printed piece work with the can/trigger?

programmers – how did the 3d printed piece work with the momentary switch, breadboard and code?  What changes did you and the CAD/CAM designer agree on for the trigger switch redesign (if necessary)?

1. For the first 30 minutes of class:

-meet as groups
-get a golf hole planning sheet
-talk as a group about what obstacles you want, what’s the path to a possible hole in one
-draw the design for the golf hole obstacles, etc.
-take a photo of your approved plan for the CAM/CAM design to blog

2. work time

CAD/CAM you are the blogger today.   You should test your printed design for fit and function with can, golf ball, switch and wiring.  Consider:
-does the switch and 3d printed trigger fit in the hole?
-does the golf ball close the switch every time?
-how stable is the switch in the can?

Make revisions and submit your new version by clicking here.  Include “version 2” in the name of your new version.

Programming – test your breadboard circuit with the 3d printed trigger switch.  Work with the CAD/CAM designer on revisions and changes.

Woodworking-

Blog post – the CAD/CAM designer is the blogger.  Use the desktop computers to update your blog – phones and tablets have been too slow too update.  You will lose points if your images and text are not uploaded at the time of your presentation.

Your blog post should include:
>images and description of your golf course plan that you created in class today
>images of your trigger switch assembled outside of the can and inside of the can
>images of breadboard and code

Today’s bloggers: Programmers.  Don’t rely on phone/tablet to post to blog as the connection is too slow. Use a desktop.

(@ 2:50 clean, login, communicate with group, collect post content, post blog)

All groups will present at end of class using blog for visuals.

Blog post should include:

woodworking: Image of clamped, drying, box with hole.  Description of your progress.

CAD/CAM: Photo of completed prototype 3d printed, with switch in place. Work with programmer to discuss design changes for version 2.  Written description of progress today.

Wiring and programing: Test 3d printed trigger switch with your breadboard.   Discuss with CAD/CAM designer and consider what revisions are necessary in version 2.  Written description of progress today.

Resources:

–Review these 3d printing guidelines before submit your design.
-If your design meets the above guidelines then you can submit it by following this link.

today

All students begin in computer lab.
All students login, review THIS agenda.
All students: verify that you can log into your blog.  Here’s a list of the project blogs. 
Woodworkers LOCK your workstation and begin work in shop.  CAD/CAM and programmers continue in lab.

Individuals work on specific tasks (woodworking, CAD/CAM, Wiring programing).

end of day goals:
woodworkers – completed, clamped box glued, hole cut (5 points)
CAD/CAM – Get a can from Varvil and measure it.  Write your group name on the can.
Submit prototype design of trigger switch for 3d printing.  Click here to submit.  Make sure that it is LEVEL on the build plate and that you have made the design PUBLIC.  (5 points)
programmers – prototype breadboard setup with circuit (5 points)
project blog post submitted and presented (5 points)

End of the day benchmarks to be blogged and presented to the class using your group’s blog post – sample blog post here

Today’s project bloggers: Woodworkers. (@ 2:40 clean shop, login, communicate with group, collect blog content, post blog)

CAD/CAM: screen shot of component submitted to be printed

Wiring and programing: Image of prototype wired or code

Here’s our team’s progress on the golf project:

Woodworking – I took the cut components and glued and clamped them.  The hole was cut for the golf ball.  My goal for the next class is to begin work on the backplate design as well as drill holes for wiring if needed.

CAD/CAM – The design for the base of the of the switch was submitted for printing.  The base provides access to contacts that can be wired before installation in the tin can.  It will also hold the switch in the vertical position and provide stability for the trigger mechanism.

Programmers -Setup our breadboard with a circuit that will trigger a buzzer sound when the trigger is activated.  Our programmer found several sources of sample code that will assist in the code building.

Today we officially begin our mini-golf hole project.

By the end of the day you will:

1. review the project descriptor
2. take the project descriptor quiz
3. demonstrate your Arduino stoplight program
4. meet with your group and make initial decisions about job assignments

Agenda

1. Take the quiz BY YOURSELF by clicking HERE.  You may use the project descriptor to aid you in completing the quiz.  One quiz per person. (5 points)
2. Find your group members and click here to complete your intro survey.  This should be completed as a group.  One survey per group. (5 points)
3. Once your group has submitted above survey then split into job alike groups.  Woodworking with Varvil.  Tinkercad and programming in the lab with Milstead.
4. The last fifteen minutes of class: each group stands in front of the class and tells us: (5 points)
   1. name of group
   2. who is doing which job
   3. what’s the hole celebration?  What action occurs when the ball drops?

working with servos

1. take a serve – share as i have a limited number

2. copy paste this code into a new sketch:

#include <Servo.h>

Servo myServo;
int servoPin = 2;

void setup()
{
myServo.attach(servoPin);
}

void loop()
{
myServo.write(90);
delay(20);
}

3. connect the servo to your Arduino like this
red to 5v
black to GND
white to pin 2

run it.  What happens?  What happens if you change the number in this line: myServo.write(90);?

project wrap up – respond to these questions in a blog post

Written response to:

What is the goal of this project?

What is the learning goal of this project?

What tools were used in the making of your stoplight?

What did you learn while doing this project?

How do you feel about your project? Did you enjoy it? Was it difficult?

What would you like to learn more about?

today

If you haven’t gotten credit for the RBG color changer finish that first.  Click here for details.  

Then the momentary switch and Arduino.  Use the momentary switch, the breadboard and the Arduino to turn on an LED.  There is no diagram or program.  Can you fly solo and figure it out?

Then move onto working with potentiometers.  

Happy Star Wars Day!! May the 4th Be With You!!

today

RGB color changing LED – you will have room on your stoplight breadboard to make this work.  Don’t remove any of your stoplight circuit.

Once you have have completed your own custom color changing sequence show me for credit.

tomorrow

1. if you want to connect your actual stoplight to your circuit bring it to class on Tuesday

2. connecting servos to Arduino and making them MOVE

today’s goals:

1. finish setting up your red/yellow/green stoplight with code.  Click here for breadboard setup and code.

2. write a blog post that shows a picture of your breadboard setup and your commented code.  What does commented code mean?  After each line type a // and a SHORT explanation of what is happening in that light of code.

3. once you have your stoplight working move on to part 2: adding the walk/don’t walk signal.  Click here for the breadboard setup and code.
