:
This shield is particularly well suited
to the experiments that you will be doing later in this chapter because it
includes both a real-time clock (RTC) chip and an SD card interface. This
shield connects the SD card to the default pin CS and connects a real-time
clock chip to the I
2
C bus (see Figure 13-11).
