Now we are going to step into the world of ICs (integrated
circuits). In this circuit, you’ll learn all about using a shift
register (also called a serial-to-parallel converter). e shift
register will give your RedBoard an additional eight outputs,
using only three pins on your board. For this circuit, you’ll
practice by using the shift register to control eight LEDs.
