2.4.2.1 Automatic Relay Switching

For simplicity in this example, the microcontroller automatically switches the relay every five seconds. In a complete application, it is expected that the Serial Peripheral Interface (SPI), Inter-Integrated Circuit (I²C), or General-Purpose Input/Output (GPIO) would be used to signal when the relay needs to be switched.
