The Design TaskThis design task is separated into three parts, described as follows:Part 1For the first part of the design task, you are required to design andimplement a digital dice using a 7-segment display.The function of the circuit should be that when you press one button arandom number between 1 and 6 will be displayed in the 7-segmentdisplay.Part 2Unfortunately, not all games require a single six-sided dice. For the second part of the design task,you are to extend your initial design so that it can provide the following functions:• A four-sided dice (displays a random number between 1 and 4)• An eight-sided dice (displays a random number between 1 and 8)• A ten-sided dice (displays a random number between 1 and 10)Part 3Building on Part 1 and 2, you are required to add to your design to be able to detect patterns orsequences in the displayed dice number. Another 7-segment display will show how many numbershave occurred in the sequence. The sequences to consider include:• A repeated number. E.g. rolling 2 multiple times consecutively. The 7-segment display willshow how many times in a row a 2 has been rolled.• An incremental sequence. E.g. rolling a 3, followed by a 4, followed by a 5, etc. The 7-segmentdisplay will show the length of the sequence that has occurred.Bonus PartsConsider the following functions for an additional 10% to the mark of the final design for Part 1, 2,and 3.• The dice can also roll a zero (e.g. 0-4, 0-6, 0-8, 0-10).• Related to Part 3, the 7-segment display shows a 1 when the last 3 digits of your student IDare detected in the sequence, and a 0 otherwise. (If you wish to use the 6-sided dice fromPart 1 here, you can make any digits above 6 in your student ID equal to 6, and any 0’s equalto 1.The DeliverablesThe total mark for the lab consists of the following two deliverables:1. A functioning circuit that meets the requirements of the design task (22 marks).You will need demonstrate the function of the circuit to the lab demonstrators in lab sessionin Week 5.2. A detailed design log/journal, containing the design process and your self-reflection of theexperience undertaking the design process. The log will require periodic use and becompleted and submitted via Moodle and should include at least the following (8 marks):• A journaled description of the progress of your design. This should include the rationaleof your approach, resources that you have found, with relevant links, successful andunsuccessful attempts on your design.• A reflection and lessons learned part for your unsuccessful attempts.• Things that you had to revise from your earlier knowledge in order to proceed with thedesign task.• A table with one hundred rolls (from any of the above dices) with a graph illustrating thepatterns and (hopefully) the random nature of the number you display.• References used.• Schematics and drawings• A page with the total cost of the design.A template for the design log will be provided on iLearn. Assessment of the design log will bebased on its content and also on your consistency in updating it periodically (at least each week).The deadline for submitting the completed design log is 5pm on the Wednesday of Week 5.Design Requirements• You are not allowed to use a PC for Design Task 1.• You can build the circuit in a breadboard or anywhere else you prefer.• You can use any component you prefer for your design. However, if the component is notavailable in the list of components available by the workshop, it is your responsibility to orderand it and you must also justify its usage in your submitted log. Keep in mind, ordering maytake two weeks.Marking & AssessmentThe following aspects will be marked for your circuit:• Your circuit design, the design process undertaken, and how well the design achieves thespecifications of the design task.• Your understanding and explanation of the operation of the circuit and also of the functionof each of the elements in your design. You should be able to articulate why each of thecomponents is included and what it does in the circuit.• How organised / neat / compact your design is and how easily you can troubleshoot it.More detail about the marking rubric will be provided closer to the assessment day.
