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.
