This is the first circuit I made, the knocking sensor.
This is the second circuit I made, the moisture sensor.
Both of these two circuits require the usage of the analog input port. They are actually quite simple but how to combine them with more integrated experiment might be more challenging
Answer to the questions:
1: In this recitation exercise, I assembled two sensor circuits, which was the prototypes of sensors being connected into circuits and thus letting users get the feedback from the sensor’s process. I did two circuits, one is the knocking sensor, another is the moisture sensor. If they are to be used for pragmatic purposes, I think for the moisture sensors it could be used such as by botanists, who need to do experiment about plants and need to monitor the moisture of the soil,; for the knocking sensor, we could use it in some physical experiment such as testing the force of hitting a surface, the data ouput by the sensor can provide accurate resources for researchers.
2: At the beginning of learning, coding could be like following a recipe, especially if we don’t have any background of coding. Following examples on textbooks or given by the teachers is in fact an important way to learn as a beginner, you can draw conclusions on some similarities or essential procedures of coding. However, as you learn deeper, after you have gained basic and general skills on coding, you should start to think of creating your own coding project according to what you have acquired. Imitating is necessary as a beginner, it provides the foundation for future creativity.
3:First of all, one obvious influence is that computers can provide a lot of assistance for people, which could relieve the burden for some repeating works, such as calculating and analyzing, it free us to focus on more general works. Computer also influence how people think, big data could make influence on showing people certain types of information and thus influence their view of things, which might not be a good things, people would gget caught in informations that are worthless and can not free their mind to think independently.
