In this lesson we bring together the things we have learned in the earlier 13 lessons to create a project on the Raspberry Pi 5 that we interact with through voice commands, instead of the keyboard and screen. The project is to audibly prompt us for our favorite color. It will then audibly acknowledge our color choice, and then turn the RGB LED that color. This is my solution to the homework assignment I gave in LESSON 13.
This is the schematic we are using for the project:
This is the code we developed in the video:
