Unit #2-01

Learning Outcome

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

• start to understand the basics of programming

Review

• go over what is a computer program

  • just a set of instructions

Lesson

• go over how to use the TinkerCad Arduino simulator

• watch video, "Install Arduino IDE on Raspberry Pi"

• watch video, "BLINKING THE ONBOARD LED - Arduino tutorial #1"

• go over how to save your code and more importantly, how to back it up to GitHub

  • go over the Code Blocks chrome add-on

Activity

• install the Arduino IDE on your raspberry Pi

  • install Linux on your ChromeOS  desktop, then install arduino in it:
    sudo apt install arduino -y

• use the Code Blocks extension on Chrome

• go over how to use the TinkerCad Arduino simulator

  • watch video, "Arduino - Built in LED"

    • yes, I know there is no sound!

• for backing up your code to GitHub:

  • just copy and paste for people new to programming

  • if you have programmed before, you know this is a REALLY BAD idea

    • create repo 1st

    • clone down onto computer

      • see here

      • watch video, "Backup Arduino code to GitHub"

Daily Assignment

• for the document today, for the "schematic diagram" just leave blank

• write the "Blink" program in TinkerCard Circuits

• once working in the simulator, copy the code over to the Arduino IDE

  • flash your Arduino with the code

  • save the code and back it up to GitHub
    
    void setup() { 
        // initialize digital pin LED_BUILTIN as an output.
        pinMode(LED_BUILTIN, OUTPUT); 
    } 
    
    // the loop function runs over and over again forever 
    void loop() { 
            digitalWrite(LED_BUILTIN, HIGH);     // turn the LED on (HIGH is the voltage level)
            delay(1000);                         // wait for a second
            digitalWrite(LED_BUILTIN, LOW);      // turn the LED off by making the voltage LOW   
            delay(1000);                        // wait for a second
    }  

Extra

• if you finish early, write the "Blink" program in CircuitPython

  • this will help: https://learn.adafruit.com/getting-started-with-raspberry-pi-pico-circuitpython?view=all

    • look for "Blinky and a Button"

  • use NeoVim as your IDE in the teminal

    • sudo apt install neovim

  • create a repo and then clone it down onto your linux machine

    • git clone <URL of repo> 

    • save your code to the Raspberry Pi, just like you did for Arduino

    • then use the same commands to back up to GitHub

      • git add -A 
        git commit -m "commit message" 
        git push origin main 

• I had to do the "reset" double tap trick after I saved my program the first time, to kick start the microcontroller into submission!
