2023-02-16 (Th) EWC_Box SD card read success

I kept researching how to recognize the SD card adapter. I looked at an old project and saw that when I instantiated the SD reader, I defined the "SS" or "CS" pin. I saw this in another example sketch, but I needed to remember what it meant. The purpose is to connect multiple readers to the same data port, and the microcontroller can activate one at a time, but only the active reader will respond to serial commands. This was a different protocol than I2C which requires that all peripherals have an address. I may have glossed on the fact in previous projects because I assumed I could only have a single SPI device per microcontroller. When I changed the "SS" pin to 53, I read the card's root directory successfully.
