3.3-Utilizing_analogWrite

For this assignment you will be working with a new function, analogWrite(). Unlike digitalWrite() which only has two possible power settings for an output pin, analogWrite() allows us to use an 8-bit value for power control (up to 256 possible variations). While this is not a true analog power signal, it can be uesd to imitate analog controls.

---

Step One: Build the Prototype

Create the following prototype on your breadboard:

Step Two: Review analogWrite()

Read this reference page about the new function we are learning. Pay attention to the difference between digitalWrite() and analogWrite() (What is the primary difference in the code and which pins may be used with this function?)

Step Three: Write the Code

Write a sketch that makes the lights on your breadboard alternate continuously between three levels of light.

• Red LED
  • full power
  • one second delay
  • 40% power
  • one second delay
  • 0% power
  • one second delay
• Green LED (repeat the cycle)
• Blue LED (repeat the cycle)

Repeat this forever.

There is some starter code above to help.

Step Four: Debug and Submit

Make sure your prototype behaves the same way as the one in the video. As in the previous assignment, make a new file here on GitHub. Name it 3.3_Utilizing_analogWrite.ino and Commit it to the repository.

REMEMBER: THIS ASSIGNMENT REQUIRES BOTH A VIDEO OF YOUR PROTOTYPE AND CODE SUBMITTED ON GITHUB
