the moist sensor: we made our hands wet to test how it works.
The distance sensor:
The vibrance sensor: This is a little bit tricky since in the original diagram on the website, there’re two wires inserting into the same hole on the Arduino board. But it’s impossible for us to do this. So we need a bread board to help us. The resistor and the vibrance sensor are in parallel connection.
Q1:The moist sensor can be used in farming to text if the crops have enough water and be connected with a water sprinkler. The distance sensor can be used as measuring the height of a person. The vibration sensor can be used as measuring the pressure.
Q2: Because computer has its own language, you first follow the tutorial and then make your own variations upon that.
Q3: Computer changes people’s way of thinking, way of learning and way of socializing. For example, we are thinking more about privacy. Since we are doing almost everything online: shopping, buy tickets, order food, posting blogs, sending emails etc, our personal information is exposed to the public. The way how we learns also changes. Children now can learn piano in on a computer app, there are also online courses for students of all ages. In terms of socializing, we are now talking to someone via online chatting even more than face to face.
