Unit #2-04

Learning Outcome

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

• create a program that accepts user input

Review

• computers can do math, but what if we want to get some input from the user

Lesson

• go over what a variable is:

  • in math class

  • in computer class

    • a value stored in the computer's memory that can be accessed by a name

  • before we can use it, we need to give it a name so we can refer to it

    • unlike math class, we DO NOT use single letters

      • we use word(s) that describe what is being held

      • ex. enterButton, firstName, ...

      • see "Different Naming Conventions" below: ↓

• in TS what is var, let and const:

  • see here (or here) for technical reasons

  • if it is some kind of natural constant, make it a const 

  • otherwise use let 

  • NEVER use var 

Activity

• go over the Dice program

  • see below: ↓

Daily Assignment

• click on provided link to create a new GitHub repo

  • call the repo: TEJ2O.1-Unit2-04

• 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

  • REMEMBER: to use everything we learned so far

    • proper style and formatting

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

Extra

• do the above assignment but in Python
