AWHS Principles of Technology

Well this isn’t what I had planned.  Long story short, my fifth grader got a concussion at Walker Creek early this morning.  Kaiser, CT scan and diagnosis.  Here we are.

Please support each other, stay appropriate, one at a time to the bathroom and follow today’s plan.  Treat the sub with respect.  I want a glowing report when I get back.  Thanks.

FOR YOU today, progress towards the stoplight.

Part I

We will save our field trip for Thursday.  In the meantime, complete this simple form about the inputs and outputs of the humble stoplight.  Click here for the form.  This is a grade assignment.

Part II

You are going to have to step up and work through this tutorial.  I would much rather be there with you but…

Here’s the really good tutorial: http://www.makeuseof.com/tag/arduino-traffic-light-controller/

Get through at least part 1 of the tutorial which will provide you with success if the three lights blink one after the other automatically.  If you have success dig into part 2 of the tutorial

Before you dig in here’s some useful info:

>you will be responsible for a blog post about your work today.  This is a graded assignment. Your blog post must include:

• your OWN code pasted into the blog post
• a picture of your breadboard and your Arduino wired up
• BONUS: video of your lights working

1. grab your Arduino envelope and write your name on the envelope.

2. you will need some items (listed on the tutorial) to make this work.  LEDs, resistors, jumper wires and buttons are in the clear bin on the center table.  If the bin is NOT there then please go into the office and bring it out.  Grab what you need and put it in the envelope when you are done.

LEDs not the right colors?  That’s ok – just get three of them.

3. resistors: you need to make sure that you use a 10 ohm resistor that looks like this:
The colors are brown-black-orange.

today

1. Arduino and breadboards are assigned: you will each receive a numbered Arduino and breadboard.  YOU are responsible for the condition and care of your equipment.  At the end of class return your Arduino and breadboard to your numbered envelope.  Include any loose parts as well.

Write your name under the # on your Arduino storage container.

2. Clean up all other material and return it to the proper containers at the end of class.  We all leave when the classroom is clean (but not before the bell).

3. Pick a black USB cable and put it in your envelope.

4. Log in.  Search for and start Arduino.

5. Connect your board to the computer using the black cable.  USB ports are on the back of the computers.

Grab an Arduino, a breadboard, a red LED, a resistor and a black USB cable.

Sit down at a computer, log in.

Wise use of an Arduino board – unplug the Arduino from the computer BEFORE you connect anything to board or breadboard.  Then plug it back in.

Today both Milstead and Varvil’s sections will be working on the same assignment.  Your work will be to familiarize yourself with the foundations of computer programming through self-paced online work.  Note that your work and progress today will be recorded and all work is graded.

Here’s how your work will be graded:

-20% creating your account
-40% completing stage 2
-40% completing stage 3

Part 1 – create an account at code.org: 

To earn credit for this work you must register via this link.  If it does not open in your browser you may copy and paste this link directly: http://studio.code.org/join/HGSLVH

Part 2 – Code Studio work

Login to your code.org account and begin course #2.  Complete the following by the end of the class today:

-stage 2 – all sections
-stage 3 – all sections

Do not complete stages 1 or 2.  These are paper based activities and will not be graded.

Create a lidded box – this is a skill that we will use for your next project – the 3d printed structure

finish your flash drive if you are not done

begin the 3d printed structure

Start designing.  Begin by designing the space (hole) that will hold the flash drive itself.  This is a good time to measure the flash drive AGAIN.  Measure twice, cut once.  A significant part of your grade is based on how well your measurements accurately allow for the flash drive to be hot glued into the 3d print as well as how well the flash drive fits into the USB port.

After you have built the hole you may begin designing the outer case.  Don’t start with the case design until you have finished the hole and CHECKED YOUR MEASUREMENTS.

today:

Part 1 (15 minutes)
IF your keychain printed then add the following to your blog:
-a photo of your keychain
-a description of what you learned – be specific about what you learned about 3d printing and what was the same or different between your tinkercad.com and your 3d print.
-a description of what you would do differently

Part 2 (30 minutes)
1. measure for your flash drive project – click here to learn how to use the calipers

2. complete the flash drive project worksheet with your measurements

3. draw your final design on the worksheet and include measurements in millimeters.  Limit your design to no larger than 90mmx60mmx20mm.  Keep in mind that the flash drive holder has to fit in ALL USB drives.

4. begin your design work.

designing your keychain PLUS custom images 

Intro to 3d printing

setting up your tinkercad.com account

1. USE THE CHROME BROWSER

2. point your browser to www.tinkercad.com

3. click on the “create free account” button. Note that you must be over 13 to create a tinkercad.com account.

Your LAST day of 3d modeling and printing.  For now.  On Monday you will go to Varvil’s room.

TODAY use your time wisely as you have three tasks to accomplish.

1. finish your Dream Structure

2. start – and finish – the Kinetic 3d printed piece

3. write a summary blog post that describes:
-what you learned about what can be done with 3d design and printing?
-what you learned about the limitations of 3d printing?
-what you would like to do  next in this class related to 3d printing?
