Submission of

Assessment

Electronic Management of Assessment (EMA): Please note if your assignment is

submitted electronically it will be submitted online via Turnitin by the given deadline.

You will find a Turnitin link on the module’s eLP site.

Important: You must also complete and submit the provided Assignment Coversheet

with AI Declaration, clearly indicating your use of AI tools, if any, as outlined.

The assessment also includes a demonstration of the working of your hardware.

Details of the arrangement of this session will be provided during the workshops.

It is your responsibility to ensure that your assignment arrives before the submission

deadline stated above. See the University policy on late submission of work.

Instructions on Assessment:

You are designing solutions for a smart home security system and are responsible for developing a proof-ofconcept prototype. This burglar alarm system should be able to detect motion and control various security

features in a smart home, such as activating a sound alarm, flashing lights, and activating a motorized

security feature. Additionally, the system should use serial communication to inform people about a breach

and ask for input to take specific actions.

You are provided with an Arduino UNO or an UNO WiFi Rev2 board, a PIR motion sensor, a buzzer, a DC

motor (with a transistor and flyback diode), a push button, a single RGB LED (or three individual LEDs), and

resistors (330 , 1K and 10K).

You are expected to detect motion and control alarms as follows:

Requirement

Motion Detection Use the PIR motion sensor to detect movement.

When motion is detected, activate the buzzer to simulate a sound alarm and

the DC motor to simulate activating a security feature (door lock, vault

mechanism, window shutter)

Light Control Use the RGB LED or three individual LEDs to indicate system status as

follows:

o Red for "activated” alarm system

o Flashing Blue (every 0.5 seconds) for "motion/breach detected"

o Green for "deactivated" alarm system

System Control Use the push button to reset and deactivate the security system

Serial Communication Use the serial port to inform people about a breach

Ask for input via the serial monitor to take specific actions:

o Reset the system (r)

o Deactivate the alarm (d)

Enter.

Additional Instructions to students:

You will be expected to produce a short report on this project explaining your methodology and the key

elements of your code. Your submission for this module should contain:

1) A well-formatted flow chart, which shows the key concepts of the code (1 side of A4).

2) A circuit diagram using Fritzing or TinkerCAD.

3) A short report (maximum 1100 words including the tolerance) which explains the main points of your

code and how you developed it.

4) A complete code listing with annotated and commented code. Please insert the code as text, do

not insert a screenshot of the code. The code should go in an Appendix section at the end of the

report and will not be counted towards the above word limit.

You will also have to demonstrate the working of the device in person on Monday 19 May 2025. Further

details about the demonstration arrangements will be provided closer to the date.

Marks will be awarded for presenting a working device and a clear report showing understanding of the main

concepts (see assessment criteria). Please note that this is an individual coursework.

ASSESSMENT REGULATIONS

You are advised to read the guidance for students regarding assessment policies. They are available online

here.

Students can use AI tools as per the statements in the Assignment Coversheet with AI declaration and

declare usage therein, by using the checkboxes and completing the designated spaces therein.

Late submission of work

Where coursework is submitted without approval, after the published hand-in deadline, the following

penalties will apply.

For coursework submitted up to 1 working day (24 hours) after the published hand-in deadline without

approval, 10% of the total marks available for the assessment (i.e.100%) shall be deducted from the

assessment mark.

Coursework submitted more than 1 working day (24 hours) after the published hand-in deadline without

approval will be regarded as not having been completed. A mark of zero will be awarded for the

assessment and the module will be failed, irrespective of the overall module mark.

These provisions apply to all assessments, including those assessed on a Pass/Fail basis.
