The first sensor that had caught our eyes was the moisture sensor. It was kind of hilarious of how after we finished building everything the sensor could not test out the humidity when I put it on my hands. We doubted ourselves for a second. Then later we found out that because my hand was too dry, so the sensor did not work. After I poured water on my hand, then the number went up tremendously. Since the moisture sensor can test out the humidity, so I think it is a useful tool for people who constantly need to figure out the level of humidity and collect the data for their work. In this case, people who work for weather casts might find moisture sensor to be very useful. They would use the moisture sensor because it could make their jobs easier by collecting the nearly most accurate data for them.
Coding, unlike writing, it does not have the freedom to let you spit out whatever is in your mind as long as you are logically making sense. When you code, of course there are several coding options for one task. But you do have to follow the guideline. For example, you have to start a statement then close it properly. Otherwise, an error message would appear on the system. This is no different from cooking. Whenever you cook, you also have to follow the guidelines even though you also do have several options lying ahead of you. But heating up the pan, then pour oil, etc, are the processes that can never be skipped.
Computer exists everywhere in these days. A lot of us rely on computer in many ways, such as collecting data for work, recording documentations for a class, finding out the outside world, etc. Computer makes our daily lives much more convenient and opens up so much more opportunities for us.
