Summary Of System Conections
Each of the systems is interwoven into the main function of the product, to make coffee. The water pump and heating system gets the water hot and delivers it to the brewer. The Circuitry and input system tell the brewer what to do and when to do it. The grinder and filter get the beans ready to be brewed. And the brewer takes all of this and puts it together into one process that brews coffee. Below is a chart that demonstrates the systems and their connections.
