AWHS Principles of Technology

Sample code – serial terminal with IF/ELSE

Quiz/Schematic review

Last day of outputs

Goals by end of class:

1. Minimum goal by end of class to earn a B grade on this unit: complete factory challenge – use the Factory Challenge Help Desk with Mr. Varvil.
2. Eligible for an A grade: Click here to Play a Scale on an Arduino.  Can you modify the program to play a SHORT tune?  Build this circuit NEXT to your Factory Challenge circuit or on a separate breadboard.  Do not destroy your Factory Challenge circuit.
3. Controlling Sound with Light using an Arduino  Use a photoresistor to control the sound output from a piezo buzzer.  Build this circuit NEXT to your Factory Challenge circuit or on a separate breadboard.  Do not destroy your Factory Challenge circuit.

End of period – turn in boards with your name.  We will evaluate your boards based on your progress.

Test day

After you finish your exam please continue your work on the Factory Challenge and the Pendulum Challenge.

Done?  Great.

You have controlled a motor and LEDs with an Arduino.  Now it’s time for sound.

Click here to Play a Scale on an Arduino.  Can you modify the program to play a SHORT tune?

Controlling Sound with Light using an Arduino  Use a photoresistor to control the sound output from a piezo buzzer.

Arduino Blink

Challenge 1: Click here to program your Arduino to blink the onboard LED

Challenge 2: Click here to program your Arduino to blink an LED on a breadboard

Challenge 3: Blink multiple LEDs on your breadboard

Extension activity: see Mr. Varvil for a schematic that will help you to control with and Arduino program.

The Arduino Introduction assignment must be submitted BEFORE CLASS on Thursday, March 16th for credit.  You will watch a short video and then complete an online worksheet.

You need to watch this video.

Fill out this online worksheet.

 

 

Wiring Diagram Resources:

How to Read a Schematic – Sparkfun  – a VERY comprehensive description of common wiring diagram symbols.

Make Magazine: Going From Schematic to Breadboard – includes photos of the component next to the symbol.

Today – new Inkscape tools:
>bezier tool
>node tool

New project: the laser cut puzzle

today: I will hand out the latest batch of rings at the end of class.  Laser cutting first!

Use Inkscape to create a laser cut and engraved bag tag/name tag/gift/keychain.  This can also work as a great Valentine’s gift.  What follows in an outline or cheat sheet of our process.  We will go through this step by step.

1. FIVE MINUTES! download the image of your choice from Google images.
   images that work well are:
   -logos
   -line drawings
   -black and white clipart
   -silhouettes
   -Valentine’s hearts, cupids, etc.

images that DON’T work well:
-color photos
-dense black and white photos
-anything with a watermark

2. Save your image

3. draw a rectangle/square/circle/star shape – no bigger than 2.5 inches x 3.5 inches.

4. in Inkscape, use File, Import to include the image that you saved earlier

5. work with Mr. Milstead to place the file and size your design correctly

6. change all cut lines to .001 of an inch

7. use File, Document Properties to size the document correctly

8. save your file as a PDF (Portable Document Format)

9. email your PDF to drakelasercutter@gmail.com

today: 3d printed Magnetic Ring

skills you need:
-aligning objects
-accurate measurement
-placing an object on the build plate

what images work well?

Next project: 3d printed Magnetic Ring

revise and resubmit keychain prints as needed
