Unit #2-04

Learning Outcome

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

• make an RGB LED light up from your Arduino

Review

• single LED on breadboard

Lesson

• RGB LED has 4 legs

  • 1 common ground

  • 3 legs for red, green, blue

Activity

• nil

Daily Assignment

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

  • Draw the schematic diagram

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

  • Build the real circuit on your breadboard

    • then code it!

      • rotate through each color:

        • red, green, blue, then red-green, green-blue, blue-red and finally red-green-blue (or white!)

• remember, your RGB LED has 1 GND and 3 other legs; you also need a resistor for each leg besides GND

Extra

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