The alarm module will provide an audible alarm tone [9]. This module is designed to send a
pattern of audible sounds through the speaker till the patient responds by pressing the button to
access the poach for the pills/capsules. An LED is also provided to blink during the alarm
process. A visual display string is provided for the user to read the instruction.
A second alarm is provided to prompt the caretaker to load the pills/capsules when the number of
pills/capsules in the storage unit falls below the threshold value. The number of pills/capsules
threshold value is also programmable. This alarm does not provide audio but gives a warning by
blinking.
