    Demo: Blink

     

    Google Classroom:

    Link

    Coding App:

    BCS Arduino Cloud

    Assignment #1:
    Load Blink
    Save Blink as SOS
    

    Modify the code to blink 3 shorts - 3 longs - 3 shorts (Morse Code for S-O-S)

    Modify the code to blink Your Name in Morse Code
    

     

    note: make a short = 200ms

     

    Turning in Sketches to Google Classroom:

     

    To add your Arduino code directly to an assignment in Google Classroom, you can use the Share to Google Classroom button built directly into the Arduino Cloud Editor. This integration requires an active Arduino Cloud School Plan. [1, 2, 3]

    How to Turn in Your Sketch (For Students)

    Open your project: Log in to the Arduino Cloud and navigate to the Sketches tab to open the code you want to submit. [1, 2]

    Add documentation (Optional): If your teacher requested images, schematics, or project reports, you can attach them directly to your sketch inside the Cloud Editor. [1, 2]

    Click Share: Look for the Share to Google Classroom button located within the editor panel. [1]

    Choose your assignment: A Google Classroom pop-up window will appear. Select your specific class and the corresponding assignment from the dropdown list.

    Submit: Click Turn In (or Submit) to link your live Arduino sketch directly to your teacher’s gradebook. [1]

    Add code so that:
    1) with the switch not pressed the Green LED stays on.
    2) pressing the switch switches the signal to yellow for 3 seconds, then Red for 10 seconds.
    3) The Potentiometer adjusts the brightness of the Green LED
