3.9.3 Course Steps
Step 1: Install the RGB LED Strips on the Mars Rover
Now, fix the two RGB light strips to the bottom sides of the car. They are controlled by a single set of pins, so there is
no need to differentiate during the wiring process.
Step 2: Explore the Magic of Light with RGB LED Strips
Do you remember the last time you saw a rainbow? How it made the sky colorful with seven vibrant hues? How would
you like to create your own rainbow, right here in our little Martian rover? Let’s dive into the magic of light with RGB
LED strips!
You might notice that our RGB LED Strip has four pins labeled as follows:
