PWM based motor speed control using LPC 1768Omkar Rane
This code configures the LPC1768 microcontroller's PWM peripheral to generate a pulse width modulated signal on pin PWM1.5. It initializes the PWM timer and match registers, enables the PWM output, and then uses a for loop to incrementally change the duty cycle of the PWM signal from 10% to 100% over 10 steps, pausing 1 second between each step. This allows the user to see the PWM output change frequency smoothly over time.

The HALO Hydrogen Hub project is a proposed clean hydrogen production and transportation hub in the Midwestern United States led by a consortium of companies and research institutions. It aims to demonstrate production of hydrogen from renewable sources and its use for transportation and other applications. The project is expected to receive over $8 billion in funding from the 2021 Infrastructure Investment and Jobs Act and plans to be operational by 2026-2027. If successful, the HALO Hydrogen Hub could help decarbonize industries, create jobs, and establish the Midwest as a leader in clean hydrogen technology. However, the project also entails risks from any delays or cost overruns during development.

Please show the work for this question.
The Voyager spacecraft has been transported by an alien being to the Delta Quadrant of space,
millions of light-years from Earth. Captain Janeway and her crew are attempting to plot the
shortest course home. Below is a network of the possible routes through the Delta Quadrant,
where the nodes are different worlds/planetary systems and the values on the branches are the
actual times, in years, between the nodes. a. Determine the shortest route from their present
location (at node 1) to Earth (node 22). Do NOT find the permanent set; only the short route to
Earth. b. When you are finished, give the total number of years it takes Voyager to reach Earth.
Note: This problem is continued in Part Two of the problem set where you will use Excel to
