Month: February 2019

2-28-19

Goodbye February and hello March.  That was fast.

Group 1 – finish the program we started on Tuesday.  Please scroll down to the Tuesday class agenda to see all the details. I am ready to help.  After you print out your completed code please join Mr. Varvil for wiring and soldering.

Group 2 – welcome to Arduino programming.  I will give each of you a starter handout to begin your programming work.  Follow the handout to start your program and ask me questions as needed.

What does the Arduino program do?

2019 Arduino blink breakdown

2-26-19

today – quiz and learning more Arduino
Thursday – go to Varvil for soldering and circuit building

Blink Countdown
By the end of class write a program that counts down three LEDS like this:
1. all LEDs on.
2. turn off red* LED.
3. wait a second.
4. turn off next LED.
5.wait a second.
6. turn off last LED.

Focus on writing the program.  No need to build the circuit – finish the program first.

*color doesn’t matter

Your program should have comments that explain what each line or section does.

Your program should use variables.

Your program should have messages from serial monitor that display start and end of countdown.

Your program should have your name at the top of the code as a comment.

Print out your program and turn it in.  If you can’t finish today please visit me in room 127 during tutorial tomorrow.

BUT FIRST let’s take a quiz – click here for the quiz.
During the quiz you may NOT:
-look up answers anywhere
-ask another student for help
-talk to anyone but me

After the quiz:
1. using variables in a program

Welcome back.

today’s agenda:

  1. multiple choice QUIZ TOMORROW: review the slideshow by clicking here.  Know the material through slide 12.
  2. Arduino recap from before break.
    1. software
    2. connecting your Arduino to the correct COM port
    3. programming – syntax (capitalization, punctuation, spelling) matter
  3. today- build a circuit with at least three blinking lights.  Each light should be programmed on its own pin.  Each light should blink on its own.  I will visit each of you to view your working circuit and program to give you credit.
  4. extension activity – program your LEDs to the beat of a song (choose your favorite ten seconds).  Use the delays and the order of the LEDs in your program to control the timing.

    TOMORROW:

    1. quiz multiple choice:
      1. which code will work – I  give you samples, you choose the correctly written line of code.
      2. which circuit is correctly wired?
      3. parts of an Arduino.
      4. parts of an LED – positive side and negative side – how do you know?
      5. review the slideshow by clicking here.  Know the material through slide 12.
    2. using variables
    3. using the serial monitor
    4. adding comments to your program

laser cutting update – please make these corrections for full credit and to receive your laser cut.  You are welcome to visit me in room 127 during tutorial if you need help. Inkscape is installed.

set the margins of your document AND save as PDF
Milo – resize your puzzle so that it is no larger than 7 by 7 inches
Rio- let’s look at your bag tag again.  The cutline still doesn’t work.
Ariana- check cutlines on your puzzle: set the cutline to one thousandth of inch
Jadiana – set the cutline to one thousandth of inch
Chloe K – the cutlines do not connect as complete puzzle pieces.
Lili- your puzzle is all cutlines including the OK symbol.  There is nothing that will engrave.

2-11-19

Tomorrow we will float penny boats and watch the marble mazes.  Then we begin our exploration of electrical circuits and Arduino.

TODAY – IF you have submitted all of your 3d printing and laser cutting work please do the following:

  1. visit tinkercad.com
  2. create an account and login.  You will need to verify your account through your own email – use your personal email.  If you already have a Tinkercad account your may login.
  3. Click on the blue Circuits button on the left side. Do not use the 3d modeling tools.
  4. Begin the tutorials.

Laser cutting updates: I am still cutting the puzzles.
Keychain adjustments 
Max set the margins of your document AND save as PDF
Olivia – the design was blank.  Let’s check it together.
Alexa  –  set the margins of your document AND save as PDF
Dyson – please send me your laser cut.  I received your 3d print file. Thanks.
Chloe -set the cutline to one thousandth of inch
Drake set the margins of your document AND save as PDF
Adriana – -set the cutline to one thousandth of inch
Lil- set the margins of your document AND save as PDF
Rio – for some reason there was not a cutline.  Let’s take a look.

Thursday’s CAD/CAM quiz:
1. the CAD/CAM review sheet
2. laser cutting:
-what software do we use – Inkscape
-what is the correct line thickness to CUT – .001 of an inch (one thousandth)
-what is the format for sending your file to be laser cut – a PDF

today’s agenda:

If you cannot finish your penny boat during class today then you may come to room 127 during Wednesday’s tutorial.  Today is the last day to work on the penny boat in class.  

  1. laser cutting and engraving intro
  2. software intro – Inkscape – it is already installed on your computer
  3. we will build a custom bag tag together 
  4. click here to submit your laser cut design

After we work together on your laser cutting you will:
1. complete your penny boat design OR

2. work on making a laser cut puzzle by following this amazing video tutorial.  

If you cannot finish your penny boat during class today then you may come to room 127 during Wednesday’s tutorial.  Today is the last day to work on the penny boat in class.
