Circuit:

1. components:  1) a Breadboard: a basic stage for building the circuit 

                                  2) a LED: if the circuit works, it can light

                                  3) a 220 ohm Resistor: control the voltage so that the voltage for the LED will not be too much in order to protect it.

                                  4) a Moisture Sensor: to identify and examine the humidity of the current environment and make it quantitate and visible on digital devices like Laptop.

                                  5) an Arduino: a computer that can send and receive information to achieve the goal of interactive command.

4. The description of this circuit: 

  We built this circuit to test the humidity of items or the environment. We connect the moisture sensor to the analog in A0 and connect the resistor and LED to the Pin 9. With the code we made, when the humidity the sensor identified exceed 100, the LED will be lighten to show that it is too humid. 

Question:

1. I intended to assemble an LED with a Moisture Sensor in the recitation session. I think the potential pragmatic use of my combination is to monitor the humidity for plants. Once the humidity is too high or too low that are unsuitable for plants, the LED will light to remind the users of emergency. This design will help users better take care of their plants.
2. I hold neutral position over the claim that “Code is often compared to following a recipe or tutorial.” This reveals that code is consists of various logically fluent steps and we need to strictly follow the instructions for building one code just like recipe or tutorial. However, code is not just about following the steps, it requires much more creativity than recipe or tutorial.
3. First of all, since we human rely on computer too much today to help us to complete a lot of tasks, we will be deeply influenced by its language–digital coding, our way of thinking will contain more logic and clear but we may lose the capability to feel the world in an emotional way. Also computer makes us see a broader world than we have actually experienced in person, thus we may act and think more comprehensive than before.
