Which of the following choices aligns best with our understanding of “Digital”?
Which of the following best aligns with our understanding of “Analog”?
The pins on your HERO board with a “~” symbol in front of them signify that they are capable of Pulse Width Modulation, (or in other words, the ability to read/write the voltage across the line from basic HIGH/LOW to a large range of values using analogWrite() and analogRead()). What components below would you want to use ~PWM for over the regular digital I/O pins? (Hint available).
Hint: Think of cases where you would be dealing with Analog instead of Digital.
Turning on a regular LED would be digital because you are setting it to either ON or OFF. However, if you wanted to set an RGB LED to be 100% Red, 50% green, and 33% blue, you would need to use a much wider range of values to get that color!
