Design, Implementation and Testing a Full Digital Instrument Assignment

Assignment Task

With this I&M project, you will progressively demonstrate the skills acquired through this course. This four-part assignment is part of your assessments for this course. In week 3 (when the tutorials/labs start) you will be given a random number that will correspond to the additional set of constraints you will have for this design project. The four separate submission deadlines are specified in the schedule of activities and is your responsibility to submit by the due date. 100 Marks will be assigned in total and these will be transformed into a percentage of your final grade as per Learning Guide.

General design specs (common to everybody)

Design and test a digital (Arduino-based) output light sensor capable to adapt and erase the ambient light. You will prove its functionality by showing an output value of zero (or close) when the sensor is exposed to an arbitrary constant light source i.e. ambient light. The design must then show a variable output when exposed to a generated fast frequency light source, in addition to the ambient light source. The frequency of the variable output must be proportional to the frequency of the fast frequency light source in presence of ambient light (i.e. not in a dark room). In other words, you can see this system as a light source frequency discriminator; it must be able to discriminate between a pulsing light source and the ambient light, i.e. ambient light, is automatically erased. An abstract/summary view is visually presented in Figure 1.

• With this assignment you will demonstrate your engineering skills, the skills acquired during this course and your capability to work
• You are going to build up the skills to fulfil this project during the lectures and tutorials, submission of milestones is devised to match the skills
• It is expected that this project will take approximately 18 hours of work during the semester, 9 hours will be spent in class where members of the teaching team will be able to assist you with your queries and design
• For this project you will be trained in the use of the instruments/software packages used in this unit for approximately 9 hours during the It is expected that you dedicate at least as much of your own time to exercising the skills acquired.
• All the tutorials are functional for the preparation of this assignment and its

General constraints (common to everybody)

• You must use the LDR sensors supplied by the school. If you want to use your own, you will need to submit a brief statement explaining the reason why you should be allowed this advantage; approval is granted by the teaching team and the decision is
• You can use up to two separate light sensors
• You can only use LM741 and/or TL081/2/4 as an amplifier for this project. Your choice must be declared and argued.
• Your signal conditioning for the light sensor(s) must be a fully differential
• Your design must be protected against aliasing, the sample rate that you must use is specified in the next
• In this project you are competing with your peers, as part of this assignment you will need to submit a 3 minutes video of you presenting/demoing your project/circuit. The aim of this presentation is to convince the project managers (teaching team) to select your project/circuit for
• Arduino must be used to acquire data, for submissions 2, 3 and You are expected to show the output of the LDR(s) and the final output of your circuit recorded on the Arduino using the ADC ports (A0, A1 and A2). Note, your circuit must discriminate the ambient light using your analogue circuit design, and not via code.
• Arduino must be used to control a variable light source (LED) and generate a known light pattern that should be visible in the acquired

Submission 1

For this submission you will answer a brief vUWS quiz composed of 3 questions:

1. In the simulation circuit diagram, for the purpose of the simulation, your ambient light is to be modelled as a DC source and the variable light as a sine wave of suitable amplitude and frequency. Tidiness and easiness of reading the schematic (must be collated on a single image if multiple pages) will be key to getting good marks, please annotate the schematic properly i.e. import in Word, PowerPoint etc. so that you can add captions!!!

2. The simulation results presented as a single graph image. It must show without doubt that your simulated circuit can fulfil the assigned specs. Tidiness and easiness of reading the image (must be collated on a single image if multiple panels) will be key in getting good marks. You should import the data from the simulation in Matlab/Excel to produce a proper plot and add proper captions/legends/labels.

3. Principle of functioning. In a few words explain how the circuit works i.e. the purpose of each stage and how the simulation demonstrates the results. You must include calculations showing how you designed your stages where applicable. Calculations, images, tables and captions are not included in the word count.

Submission 2

For this submission you will aswer a brief vUWS quiz composed of 2 questions:

1. Create then upload a Word document that includes the following three sections:

Section 1 -The functioning virtual breadboard assembly. Tidiness and easiness of reading the circuit will be key in getting good marks, please annotate the schematic properly i.e. import in PowerPoint. so that you can add captions, text boxes, graphics etc... On a separate panel, You must include the output plot(s) of your virtual breadboard.

Section 2 - The shared public link to your virtual breadboard assembly (if you do not recall how to do it please watch)

Section 3 - Principle of functioning. In a few words explain any differences between the simulated circuit and the real circuit and your preliminary results. i.e. what is the error on the real analogue measurements, and how did you tweak components value(s) to fulfil the specifications? You must include calculations of your theoretical and actual stage values (e.g. CMRR, gain, cut-off frequency, offset etc.) where applicable. Calculations, images, tables and captions are not included in the word count. Calculations, images, tables and captions are not included in the word count.

2. Create then upload a Word document that includes the following two sections: Section 1: A high-quality photo (your student ID card must be included in the photo) of your real breadboard. Tidiness and easiness of reading the circuit (must be collated on a single image if multiple pages) will be key to getting good marks, please annotate the schematic properly i.e. import in Word, PowerPoint etc. so that you can add captions, text boxes etc.

Section 4 -  Proof of functioning, you must include the output plot of your physical breadboard. Data acquired from Arduino/oscilloscope should be formatted in Excel/MATLAB to produce a plot that can be included in the document.

Submission 3

For this submission you will answer a brief vUWS quiz composed of 2 questions:

1. Produce and upload a zipped file comprising:

• Your annotated Arduino Use plenty of comments and submit your code pasted into a PDF file.
• The compile result (screenshot of a successful compilation message).
• You must supply your. 

2. Your PCB files collated into a single image. Please use proper labels and captions. Include the schematic(s) and the 2D design of your board, not a 3D rendering. If double-sided, include both sides of the board as a single image with red for the top traces and blue for the bottom traces.

Submission 4 - Presentation

For this submission, you will upload an up to 3-minute video demonstrating the circuit functioning. You should use zoom so you can record yourself talking into a webcam, using screen sharing you will be able to share the screen with your schematic and functioning circuit uploading data via USB as well as any slides you want to use to explain your design. In this video, you can also detail and explain why your circuit does not behave as expected/major deviation (>10%) from the specs. In the video, you should demonstrate the full functioning circuit with variable light frequency (LED) in day/room light with a variable light frequency of α Hz. 

Your variable light frequency is α corresponds to a numeric value (see table below) corresponding to the first letter of your given name as per student ID. To remove any ambiguity, please refer to the following table showing the correspondence between letters and numbers:
