Task 1) Report
Provide a short report (maximum 2 pages including references) that answers the following question:
What are the differences between the following processor instruction sets?
Include the following aspects:
• Timing
• Number of instructions
• Processors using each approach
• Advantages and disadvantages of each approach

Task 2) Pelican System
You need to design a Pedestrian Light Controlled Crossing (Pelican) system using the flowchart method and then implement this using Arduino UNO. The specification of what is required is as follows:
• Design the circuit of the Pelican system, which includes an Arduino UNO, LEDs and other necessary components. The system has two sets of lights, one for car drivers (green + yellow + red LEDs) and one for pedestrians (green + red LEDs).
• Connect the components as designed.
• Write the code for the system. If a button is pressed by a pedestrian, the traffic lights should work following a standard UK sequence.
• More advanced features can be added into the system to improve safety and practicality.
Notes: You can also write debug commands to the serial port so you know what is going on.

Task 3) Automatic Swing Door
You need to design a simplified ‘automatic swing door’ system controlled by an Arduino UNO. In the system, a light dependent resistor (LDR) is used to detect an object approaching through the change of light brightness. A servo is used to simulate the operation of an automatic door, and an LED will indicate the status of the door. The specification of what is required is as follows:
• Design the circuit of the system, which includes an Arduino UNO, a servo motor, an LDR, an LED and other necessary components.
• Connect the components as designed.
• Write the code for the system. If an object approaches the LDR, the servo will move from its initial closed position (0°) to an open position (90°); then stay at the open position for 5 seconds; finally move back to the closed position.
• An LED is used to indicate the status of the door. If the door is open, turn on the LED; If the door is closed, turn off the LED.
• More advanced features can be added into the system to improve safety and practicality.




Sample Solution

Sample solution

Dante Alighieri played a critical role in the literature world through his poem Divine Comedy that was written in the 14th century. The poem contains Inferno, Purgatorio, and Paradiso. The Inferno is a description of the nine circles of torment that are found on the earth. It depicts the realms of the people that have gone against the spiritual values and who, instead, have chosen bestial appetite, violence, or fraud and malice. The nine circles of hell are limbo, lust, gluttony, greed and wrath. Others are heresy, violence, fraud, and treachery. The purpose of this paper is to examine the Dante’s Inferno in the perspective of its portrayal of God’s image and the justification of hell. 

In this epic poem, God is portrayed as a super being guilty of multiple weaknesses including being egotistic, unjust, and hypocritical. Dante, in this poem, depicts God as being more human than divine by challenging God’s omnipotence. Additionally, the manner in which Dante describes Hell is in full contradiction to the morals of God as written in the Bible. When god arranges Hell to flatter Himself, He commits egotism, a sin that is common among human beings (Cheney, 2016). The weakness is depicted in Limbo and on the Gate of Hell where, for instance, God sends those who do not worship Him to Hell. This implies that failure to worship Him is a sin.

God is also depicted as lacking justice in His actions thus removing the godly image. The injustice is portrayed by the manner in which the sodomites and opportunists are treated. The opportunists are subjected to banner chasing in their lives after death followed by being stung by insects and maggots. They are known to having done neither good nor bad during their lifetimes and, therefore, justice could have demanded that they be granted a neutral punishment having lived a neutral life. The sodomites are also punished unfairly by God when Brunetto Lattini is condemned to hell despite being a good leader (Babor, T. F., McGovern, T., & Robaina, K. (2017). While he commited sodomy, God chooses to ignore all the other good deeds that Brunetto did.

Finally, God is also portrayed as being hypocritical in His actions, a sin that further diminishes His godliness and makes Him more human. A case in point is when God condemns the sin of egotism and goes ahead to commit it repeatedly. Proverbs 29:23 states that “arrogance will bring your downfall, but if you are humble, you will be respected.” When Slattery condemns Dante’s human state as being weak, doubtful, and limited, he is proving God’s hypocrisy because He is also human (Verdicchio, 2015). The actions of God in Hell as portrayed by Dante are inconsistent with the Biblical literature. Both Dante and God are prone to making mistakes, something common among human beings thus making God more human.

To wrap it up, Dante portrays God is more human since He commits the same sins that humans commit: egotism, hypocrisy, and injustice. Hell is justified as being a destination for victims of the mistakes committed by God. The Hell is presented as being a totally different place as compared to what is written about it in the Bible. As a result, reading through the text gives an image of God who is prone to the very mistakes common to humans thus ripping Him off His lofty status of divine and, instead, making Him a mere human. Whether or not Dante did it intentionally is subject to debate but one thing is clear in the poem: the misconstrued notion of God is revealed to future generations.
