Problem Definition: 

Goal:  

To design an alarm clock that gradually awakens the customer using lights, sounds and aromas to entice the user to get out of bed before more violent and persuasive measures are taken.

Objectives:

-To interact with the surroundings to initialize a cooling fan if temperature gets too high.

-The system will consist of three alarm stages that progress from gentle and calm using sweet coffee smells, followed by choice of buzzer or music, until vibrating pillows and 4-bar are activated.

-Easy availability for add-ons using two A/C outlets.

-Incorporate a keypad for easy inter time and alarm time along with temperature and humidity settings and music on/off functions.

Constraints: -Operate off of a 5V A/c to D/C converter. -Fit neatly into the contained space. -Quickly detect if lights or turned off or on.  

Abstract 

Our objective was to design a machine that could wake up any person, without fail, using

a series of alarms with increasing intensity. Before the series of alarms commence, a coffee pot

will be triggered to brew. Next, the sequence will begin with various auditory alarms, followed

by an alarm that will stimulate multiple senses. And, for the heavier sleepers, our final alarm will

ensure the consciousness of the consumer is achieved. The user will be able to choose which of

these alarms they would like to be active.

Design Summary

Our goal is to use sequential logic, achieved through a PIC Microcontroller, to design a

machine that would adjust the consciousness of a user during sleep through a multi-functional

alarm clock. This device will include switches and buttons to control various process

combinations. First, the user will be able to input the time, followed by an alarm time, using a

keypad. Six LEDs will indicate depressed buttons or command functions. When depressed and

the time increments to the specified alarm time, the buttons will activate two AC outputs (used

here to power a coffee maker and fan), a buzzer alarm system, pillow vibrator, music output, and

bed sheet remover all at the specified alarm times. For example, if one would like to wake up

slowly the user can program the coffee maker to come on early, so the smell of brew lingers

while mellow music begins, lead into more abrasive pillow vibrations, and for the heavier

sleeper, one could end with an obnoxious buzzer. If this proves ineffective, after a designated

amount of time a mechanism will remove the bed sheets off the user's bed guaranteeing the user's

consciousness to be adjusted. A small scale prototype for both the vibrating pillow and the bed

sheet remover will be implemented. A seven segment, four digit LED will display time, alarm

time, temperature readings, and various animations. Through implementation of Thermister the

user can select a temperature input threshold that if past will turn on an ac output that can be

either a fan or a heater. In our project, the combination of switches will provide desired

functionality, and the variety of outputs will leave the options wide open for the user. With this

machine you will never have to worry about sleeping through that eight am test, or miss the bus

ever again. Internal body clocks and standard alarm clocks are obsolete, but sleep with ease

knowing your consciousness will be adjusted by the Perfect Wake-Up Machine.

Design Evaluation

A. Output Display

The Perfect Wake Up Machine fully satisfies this category through a serially controlled four digit

seven segment LED that acts as a clock display, and also six pushbutton LEDs. The LEDs in the

pushbuttons are activated when the button is depressed, to indicate which alarm the user would

like active. The LED clock display is easily one of the most important parts of this project. The

display will read the current time, allow you to set the current or alarm time, and it will read the

room temperature, humidity as well as set a threshold temperature.

B. Audio Output Device

This project has multiple audio outputs, featuring two speakers on the front which play music, a

buzzer which acts as one of the alarms, and one additional speaker which sends out a beep when

a keypad button is pressed. The keypad beeper was achieved using an EDE1144 keypad encoder,

which has a pin devoted to making this sound. By design the user can plug in an audio jack

straight into the machine and have it play music through the front speakers. This music can be

used either as an alarm, or can be turned on and off using the keypad at any time during the day.

C. Manual Data Input

Once again, The Perfect Wake Up Machine shows several elements of this category. The main

manual data input is a 3 x 4 keypad, which allows you to enter time, check the temperature

(Celsius or Fahrenheit) or humidity of the room, set a threshold temperature in Fahrenheit, adjust

the brightness of the clock display, and turn the music on or off.. The device is wired through an

EDE1144 keypad encoder, which reduces the number of pins that go to the master PIC to two.

16 

Other data inputs include the six pushbuttons which activate the various alarms, a snooze button

used to delay the sequence until the next alarm, and a 'kill' switch which disables the alarm. A

potentiometer was used in the amplifier circuit to control the volume coming from the music

speakers. Also, digital potentiometers were used to control the dimness of the LEDs. The

potentiometers were controlled using a PIC microcontroller, which read the resistance value of

photo resistor. After reading the photo resistor the PIC would either make the potentiometer use

a high resistance or a lower one depending if it was light or dark. If dark, the maximum

resistance will control the LED lights to a dimed value compared to the brightness it will exhibit

if the light sensor is lit. The dimming of the lights allows the user to see the display and buttons

at night, but not be blinded while attempting to sleep.

D. Automatic Sensor Input

This project has two sensor inputs, one simple and one more complex. The simple sensor is a

photo cell, which changes resistance values depending on the light. As the light decreases, the

resistance of the photo cell increases and visa versa. The cell was used to control the brightness

of the LEDs, as was talked about in the previous section. The other sensor was a SHT11 digital

humidity and temperature sensor, or thermister. With this devise, one could measure the

temperature and humidity in the room easily at the push of a button on the keypad.

E. Actuators

Again, this functional category was satisfied multiple times in our design, both in the form of

motors. To activate the motion of the four-bar bed sheet remover, one on-off DC motor was

used. As the final alarm this motor is activated using a relay to quickly pull off the bed sheets.

Another component that used motors is the pillow vibrator. The vibration is achieved using five

17 

of the small vibrating motors used to make cell phones vibrate, which are placed in a block of

wood to resonate the sound and vibration.

F. Logic, Counting, Integration, and Control

The final category was the most essential, and also the most time consuming part of this project.

To control the multiple outputs in the system, multiple PICs had to be used. A 40-pin master

PIC16F747 communicates serially with 2 different slave PIC16F88s to activate the various

alarms. Each slave PIC contains a small amount of code, but the master PIC required more

extensive programming to do all of the desired tasks. Counting had to be used in a couple places

in the project. The master PIC was used to generate a time that counted at the same rate as a

clock in the LED display. The SLED-C4 LED display comes with preprogrammed functions,

which helped to utilize it as a clock. However, a lot of programming went in to making the

machine count, as well as act like an alarm clock and display temperature. Another place

counting was used was in the potentiometers. The digital potentiometers require a clock input, so

a 555 timer was used to create a pulse train. Another element that fits in this category is the fact

that this device runs on logic, which was all done with programming. The entire alarm sequence

is based around logic. For example, if none of the buttons are pressed except for one, then the

code will check each alarm case and then only activate the one corresponding to the depressed

button. Alternatively if every button was pressed, the code would go through and cause each

alarm to go high in turn. And finally, code was used to quickly turn off and on a DC motor,

through a relay, so the actuator would only be active for a second.
