This time I cooperate with a foreign boy. Being a senior, he really had a good command of his computer and that really raised our efficiency. As a result, we tried five kinds of sensors this time!!!
Variable resistors:
Hardware Required
- Arduino or Genuino Board
- Potentiometer or
- 10K ohm photoresistor and 10K ohm resistor
- built-in LED on pin 13 or
- 220 ohm resistor and red LED

then we decided to change the LED into BUZZLE and make some noise!

Ultrasonic Ranger:
Hardware Required
- Arduino or Genuino Board
- Ultrasonic Range Finder
- hook-up wires

Grove – Moisture Sensor:
At the first , we are quite confused about how is it about, for the components in the introduction is different from which we have.However, we tried to connect it directly, and get a good consequence.

Infrared Distance Sensor:

Analog joysticks:
so at the end we decide to choose the hardest one.
To begin with, we are kind of confused for connect which line from all this mess. Under the help of the team next to us, me finally figure out how to handle it.
Question:
Q1:This time we try to change the LED in the first circuit into BUZZLE, we successfully make it. Then we try to change the LED into a fan (with driver), but we could not cross the obstacles of coding. Moreover, I came up with the idea that we can combine the Variable resistors and Moisture Sensors and make a machine to compute how much water we need when we water the plants.
Q2: Because the language for coding is so simple and straightforward. the computer will compute just follow these lines, which hold a clear logic. So once you get it clear that how to read it, you can just consider it as a recipe or tutor.
Q3:From one side, compute is the most important helper for modern people. It undertake a lot of labor and assist the advanced science. From other side, its convenient and efficiency trap some people in the virtual world. All in all, the huge influence it give to the human society is definite.
