One on One

Mr. B. will call students in random order to work one on one with any of:

  • Python
  • Blender
  • Tinkercad
    • Codeblocks

The rest of the class can watch or create something of their own. Ideas (from past lessons):

  • Continue the silly sentences program
  • Use Python with Blender to create various objects in a scene
  • Use Codeblocks with Tinkercad to make something

Using this example if you like, make a greeting or “thank you” card with p5.js, or use any other programming language or environment, such as MakeCode Arcade, Python, Phaser, Scratch, or Snap! to make a card.

Remember that when you use web-based environments, your programs may be visible to the public, so don’t write anything that should be private.

Notice that the snake game now has sliders you can move. Let’s learn how to create them.

Things you might control with sliders:

  • red, green, and blue color amounts
  • translations
  • rotations
  • numbers of objects
  • speed of movement

Use one or more sliders and describe what you did in a class comment in Google Classroom.

Introduction to Python

Soon we will be programming the Circuit Playground Express with Python (instead of MakeCode blocks). Let’s review (or learn for the first time) Python.

  • In a new browser tab, open
    • repl.it
      • Log in with the Google icon
      • Skip the questionnaire
      • Push the New Repl button
      • Choose Python (not Python 2 or Turtle)
      • Push Create Repl

    • Getting Started with Python (class Python web page #2)

      • Copy and paste Hello, World and other code fragments from here to repl.it and try them out. Experiment. Make changes.

Students as Binary Digits

Seven students will come to the front of the class and represent the powers of 2: 1, 2, 4, 8, 16, 32, 64, and 128. One or more students will be calculators, and will stand at the whiteboard. I will give them a message to encode, letter by letter. They will display the binary representation of the letter’s ASCII code with 0s and 1s held in front of them. The class will decode each letter, and type it into RoomHelper 3000.

Here are the ASCII codes, in decimal (base 10) for the letters of the alphabet:

a: 97     h: 104    o: 111    v: 118 
b: 98     i: 105    p: 112    w: 119
c: 99     j: 106    q: 113    x: 120
d: 100    k: 107    r: 114    y: 121
e: 101    l: 108    s: 115    z: 122
f: 102    m: 109    t: 116 
g: 103    n: 110    u: 117

Multiplayer Finger Drawing with Computer Vision

I’ll have a video camera at the front of the room. Three students will come up at a time to draw with their fingers. Each student will have a small colored piece of paper taped to a fingertip. They will hold it to the camera in the middle of the scene so we can calibrate the color recognition. Then they can draw.

Reminder of last week’s binary representation and decoding lesson

There are two options today: a computer vision exercise with OpenCV and Python, and an easier exercise with CPX. Do one or both.

Computer Vision

After having you manually decode the secret message from changing patterns of bits on the CPX, I had the thought, “Why not write a computer program to see and decode the message, and make it really fast”. Here’s the result:

Here’s an explanation:
