Projects under consideration
Fish Tank Feeder
Projects under consideration
Fish Tank Feeder
• There are three possible operations desired.
• The fish tank project is a position sensing
apparatus through IR, that once sensed, the
feeders will then dispense food controlled
through proper timing.
• The objective of the Water Institute is to
collect data that supports there
understanding of fish activity.
Projects under consideration
Smart-Bot
Projects under consideration
Smart-Bot
• A Smart-Bot is one that makes movement
based on the programming of the
interpretation of sensors.
• This fully automated robot may also be used
in tracking and following sensors detected
on a person to cart personal belongings.
Projects under consideration
Room Temperature Control
Projects under consideration
Room Temperature Control
• This project is geared towards temperature
control.
• Is able to moderate the temperature of an
environment using a thermocouple and fans
as temperature makes slight changes.
• The controlling centre would be used
through remote digital operation to set and
shut down the system.
Proposed Selection
Photo Sensing Blinds !
Proposed Product Summary
Photo Sensing Blinds !
• The blinds will be able the detect changes in
sunlight from the inside and out, and adjust
there direction by the use of servo motors.
• The blinds will operate under direction of
the CPU with proper interruption from a
remote controller.
• The blinds are to be fully automated to
operate in timed intervals that may be set
from an RF controller (optional).
Proposed Product Summary
Photo Sensing Blinds !
• The product will operate off of three photo
sensors positioned on or around the blind.
• The primary benefit of the product is to
control the opening and closing of the blind
and also to provide a glare free environment
at low cost.
• The user friendly remote control will be
made available for manual operation so that
all may enjoy!
Proposed Product Summary
Why we chose the Photo Sensing Blinds
Project ?
• Overall, this project incorporates the expertise
available of all of the group members.
• The project completion is obtainable within the
allotted time for the class.
• This project was ideal because of the possibility
of funding from the “Discovery World” and the
chance upon completion, display of the project
at there facility.
Major Risks taken
• Having made agreements with “Discovery
World”, gives a sense of obligation that will be a
challenge.
• Added product reliability and durability for
display.
• Programming limitations may prohibit our final
prototype’s range of ability.
• We must provide a precise cost determination due
to funding and might not get a second chance.
Project Selection
Why we rejected other ideas ?
• Other projects required more understanding of
resources that were beyond our present scope
(i.e. smart-bot and the fish tank).
• Repetition.
• No funding was available.
• The other projects just didn’t offer a large
enough range of product use and availability.
System Level Requirements
Performance Requirements:
• Auto mode: consistent updates from the light intensity read
sensors which cause specific angle adjusts to be made on the
motors through proper programming.
• Manual mode: fast responsive user interface through remote
control†, with push-button user settings to change orientation of
the blinds.
• Sleep mode: goes into hibernation to the extent of timers
manual setting.
• Off mode: option for the user to turn off the blind control
system completely
† Radio
Frequency remote control is optional.
System Level Requirements
Standard Requirements:
• Temperature: -40°F -> 85°F
• Humidity range: 0-100%
• Input voltage: 120V
• Power: 20W

• Motors – Nathan Schultz
 A digital input of 12Vdc nominal from
the power supply will drive the motor op.
 Wiring from the main PCB will determine
Bi-directional operation.
 PWM supplied output will be supplied
from the MPU and interfaced trough a
H-bridge to operate the motor.
