Unit #2-05

Learning Outcome

At the end of this lesson, you will be able to:

• create a program that accepts user input and does basic mathematical calculations

Review

• variables

  • we call "=" , "is assigned" not "equal"

    • some_var = some_var + 1 

Lesson

• go over using variables and doing calculations

  • we know the computer can do basic math with numbers, now lets replace the numbers with variables

Activity

• go over the "Light Percentage" program

  • see below: ↓

• go over Math.round() 

  •  you might to use floor or ceil as well

Daily Assignment

• click on provided link to create a new GitHub repo

  • call the repo: TEJ2O.1-Unit2-05

• create a program that will do the following:

  • when the user clicks the "A" button, the Micro:bit goes and gets the current temperature, saves it to a variable and then show the temperature to the user

  • the problem is we learned that the SI unit for temperature is K, not C

    • so convert the celsius temperature to kelvin

    • formula

    • don't forget to round off, so there are no decimals!

  • REMEMBER: to use everything we learned so far

    • proper style and formatting

    • ENSURE your units are done correctly (space between value and units: 15 K)

Extra

• do the above assignment but in Python
