As we conclude, here is a list of questions for you to test your knowledge regarding this chapter's material. You will find the answers in the Assessments section of the book:
- Your APA102 LED strip is set to show all LEDs as white, but instead, all of the LEDs look reddish. What could be the problem?
- What limitation does the APA102 place on SPI?
- Your APA102 does not work when you use a logic level converter but appears to work when you connect it directly to the MOSI and SCK pins on your Raspberry Pi (hence bypassing the logic level converter). What are some possible causes of the problem?
- What is the basic process for creating and displaying an image on an OLED display using the Luma OLED library?
- What is RTTTL?
