The remote unit is a little more complicated. At the heart of its design is an Atmel
ATmega162v microcontroller. It receives its data from the same Atmel transceiver that is in the
Base Station as well as five user navigational buttons on the device. From this, it decodes the
signal and controls the menu displayed on the LCD module as well as the status of the
notification LEDs as shown in Figure 1-2. The remote device also transmits order information
and confirmation through the RF link.
