Unit #2-03

Learning Outcome

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

• make a single LED light up from your Arduino

Review

• single LED on a breadboard

Lesson

• we can use the Arduino to power our breadboard and circuits and add code to it!

  • watch video, "Blink an LED With Arduino in Tinkercad"

• go over comments in code

  • so other people can understand your code

  • we will always add a comment header to the start of our Arduino programs

    • /*

        Turns an LED on for one second, then off for one second, repeatedly.
      */

  • do not go overboard with comments though

Activity

• nil

Daily Assignment

• You are now going to go through the process of creating a circuit with a single LED (and resistor, so nothing breaks) using an Arduino as the power source

  • Draw the schematic diagram in Draw.io

    • use GitHub and VSCode Draw.io extension

    • use the arduino_uno.drawio file below for the Arduino UNO schematic

      • use "import" to get it into Draw.io

      • select "More shapes, electrical" to get the needed electronic shapes

      • connect your components to the "edge" of the correct circle connectors (see below)

  • Draw the breadboard diagram in TinkerCad Circuits (see below)

  • Build the real circuit on your breadboard

    • then code it!

• remember, your LED will only work if the "long" leg is pointing to positive

Extra

• if you finish early, write the above program on your CircuitPython board
