For this week’s recitation, we built three circuits with Arduino.

Materials:

• 1 * Arduino Uno
• 1 * USB A to B cable
• 1 * breadboard
• 1 * buzzer
• 2 * LEDs
• 2 * 220-ohm resistors
• 2 * 10K-ohm resistors
• 2 * pushbuttons
• A handful of jumper cables

Circuit 1:

The first is a simple circuit to connect an Arduino and a breadboard, and the code is to fade the lights. Connect the 220-ohm resistor and a LED to the circuit, and one end of the wire is connected to the ground, another is connected to the pin9. We succeeded on the first try, we studied the code for a while to see how it worked.

Circuit 2:

And for the second circuit, it basically turns the LED in the first circuit into a buzzer. The code we use is to make the buzzer play a piece of music. It is so funny to hear that there are different kinds of music playing all around the classroom. And we couldn’t hear it very clearly at first because of the poor contact between the cable and breadboard. When the short music was being played, we felt very excited.

The buttons are connected with 5V for the power and also connected with pin11 and pin10 respectively for input. Two LEDs are connected with resistors for limiting the current to protect the circuit and also connected with pin2 and pin3 respectively for output. The buzzer is connected with pin8 for output.
Circuit 3:

It is very complicated and needs a lot of time to make completed.

The biggest problem we had when connecting this circuit was that the wires tended to fall out and the connections were fragile, so we spent some extra time checking every component and every wire connection. At first, we only had sound but no lights when one side won the game, so we checked that the link was wired correctly and that the LEDs were working. Then we changed another cable and LED, to make the whole thing even more stable. Finally, we succeed.

Question 1: Another kind of button could be the cardboard button we built in Recitation1. In fact, we did try, connecting the cardboard buttons to the circuit. We tested the game again and we found that using the cardboard buttons can be pressed faster than normal buttons. Loki changed his buttons to cardboard buttons, and I still use the previous button. I can win him a lot when we both use the regular buttons, but only a little when he changes the cardboard buttons. I thought of another creative button that connects a pressure sensor to the button. Pressure can only be recorded if it is good enough. This increases the difficulty of the game. According to physical calculations, “Without a computer, you can connect a button you press to a light that is on. With a computer, you can make the relationship between buttons and lights more complicated.” “For many people, the input is All they want to learn from physical computing. They are already satisfied with their ability to express themselves on a computer through a screen or speakers but feel limited by mouse and keyboard input. Input is often easier than output because perception Activity requires less energy than moving things.” The input is often so simple that people may not pay attention to the input. Building a creative button can make the circuit more interactive because it improves input and humans can have more opportunities to interact with the circuit.

Question2: Using a 10K resistor per button can effectively avoid short circuits and keep the pins from floating. A 10k resistor pulls the digital input pin down to GND when the switch is on. This way, we can ensure that the button will work properly.

The Winter Market

This fiction talks about a post-modern world with high-tech inventions, the people who live there commonly wear something very high-technical like a “black glint of polycarbonate at her wrist”, described as this fiction said, they have different kinds of thoughts and opinions. The author uses the romance of the Internet age to present reflections on the impact of a developed high-tech world.

Lise is a drug-addicted girl who also suffers from a congenital terminal illness. She relies on an exoskeleton to support her whole body. When she was found, she was dumped in the garbage because of the lack of electricity in the exoskeleton, but she did not say a word until someone kindly rescued her. go. Her existence feels inherently incomplete. If she wants to experience the life of a normal person, she can only rely on technology; if it is not enough, she relies on drugs and imagination. Only in the dream state as compensation can she get rid of the congenital pain and poverty, and experience the feeling of freedom that is almost insane. Therefore, if she wants a “normal” or even better survival, it is impossible to leave drugs and technology; and paradoxically, the realization of every dream comes at the cost of the decay of the flesh-to the “Kings” On the eve of completion, she was already on the verge of dying from drug addiction, but no one of the staff dared to persuade her to quit—continuing the dream requires capital, and she knew that her time was short, and she could only use technology to get rid of her physical body at one time. , her dream-like survival can continue, which requires unimaginably huge capital. Her method is to sell her dreams at one time, so she finds editors like the male protagonist to make “Kings”.

So from her thirst both for dreams and real feelings, I want to invent dream feelings implanted memory card, which can translate different kinds of real feelings of being existed in different kinds of environments and situations into a piece of digital information.

This kind of memory card can be implanted into people’s brains whenever and wherever they want, by plugging into recording and programming while sleeping, the state of the user’s dream can bring out and give the experience of that information to the user. Because the dream scene experience is more personal and liberal, we cannot limit and manage the setting of the scene, and it will be more difficult to avoid projects that are too extreme and harm the interests of others.

Newton’s sleep

In this story, people are trying to escape from the destroyed earth because of the serious environmental pollution problems, and there are also so many people who died from the extremely polluted living conditions. However, in my opinion, these kinds of problems, or we can be called their crises, will not only happen in science fiction, for the nowadays environmental problems, these things maybe will become true states in the future.

So I imagined there will be a wearable device that looks like a watch on people’s wrists,  but a  laser transmitter indeed.  People can use it to give out a kind of laser that can protect them from the air pollution or water pollution in daily life, just like to create a small, safe and clean area for individual person to insure their daily life not being influenced by the bad environment. But it might just fit for a short time of the environment changing, it. needs to fit in different periods of climate-changing, so the laser also needs to be iterated with the different conditions of the environment.

The Fish of Lijiang

The artificial sky of Lijiang in the fiction story makes me think about maybe we can invent a kind of airtight roomage in different places or areas in this world. It can be designed by anyone who has the right to live in this airtight box, they can make their sky or ground in any color they want. And there’s also a temperature controller that can be individually used to control the temperature of the area around individuals. So different boxes can be planted in various kinds of plants, or live different kinds of animals. Just like giving more chance and liberty to the diversity of species, maybe The Truman Show is a vivid example model of this kind of invention.

During the first week of recitation, I paired with Loki to connect and make a circuit.

As a liberal arts student, I learned for the first time that many circuit components play a vital role in the proper functioning of circuits.

The first are resistors. Resistors are mainly used to regulate and stabilize current and voltage in circuits. Since the battery provides more current and voltage than the LED light can carry, to prevent a short circuit, a resistor should be used when connecting the light.

The second is the LED. Whether the LED light is on or not reflects whether a circuit is running normally, which can help us better grasp the internal situation of the circuit and quickly respond to the circuit connection.

A variable resistor is a resistor whose resistance value can be adjusted. It is used when the circuit current needs to be adjusted, or the circuit resistance needs to be changed. In our circuit, it acts the same as a resistor.

The switch is one of the core components of our circuit. It controls the work of the buzzer and LED lights through the connection and blocking of current, and promotes the interaction between the circuit and people.

The buzzer will beep when the current is connected to the circuit. Its presence facilitates an auditory shift in the circuit. The power supply is critical to the operation of a circuit, providing energy for all components to function properly.

GND is used as the 0V reference point for different functional circuits, which helps to reduce mutual interference between circuits and form other current circuits. Finally, there is the circuit board, which is a unique design and structure that provides the medium for the connection and communication of all the above circuit elements, and the platform for forming the circuit.

In the first step of connecting the buzzer to the circuit, we found that the buzzer was not working. So we consulted the learning assistant and found that when the switch was wired, there was no diagonal line but the same direction connection, resulting in a short circuit at the switch, so the buzzer did not work. We went through the switch block diagram in the reference, changed the wiring at the switch, and finally completed step 1.

 In the second task, we carefully inserted the resistors and diodes with one of their two cables inserted parallel to each other and the other next to the connecting cable. The whole process went smoothly.

If they are connected in parallel, there will be a situation where the LED cannot be controlled, and the LED will stay on instead of following the switch.

Then we successfully finished the last task.

We also replaced the original switch with the self-made switch. Question 1:

R1 is mainly used to regulate and stabilize the current and voltage in the circuit. Since the battery provides more current and voltage than the LED1 can carry, to prevent a short circuit, a resistor (R1) should be used when connecting LED1.

Question 2:

Question 3:

I think the interactivity of the circuits we make today is that we can turn on an LED and sound a buzzer by pressing a button and closing the circuit. I find this circuit to be very interactive. When I press the button, it’s like listening to the interaction. The circuit starts thinking from my instructions, and finally speaks the information in the form of a buzzer and LED, forming a benign interaction between information and between people and circuits.

Question 4:

Interaction design and physical computing create media and platforms where humans resonate with the digital world, providing tools for the transformation of information about human behavior and the creation of interactive art. Just like a human-computer interaction technology called Eyewriter launched by Zack Lieberman, it can capture the focus of the line of sight and use the eyes as a brush to write and draw, not only to help paralyzed patients better express their personal needs but also to promote interaction The creation and development of art. The application of interaction design and physical computing expands practical human tools, enabling humans to create more colorful art.

      As I have read all three readings and watched many videos about interactive arts. The most impressive thing left in my mind was the action of response among different figures or entities in the whole interactive process. It is definitely that giving out and analyzing information then giving back the actions are the most important components in interactive art pieces. Then, when we talked about the definition of interaction, Crawford has talked about it in terms of a conversation in The Art of Interactive Design, “a cyclic process in which two actors alternately listen think, and speak”. However, I think it’s a definition in the context of pre-electrical society, which means the nowadays interaction can be defined on a large scale of electrical device and alive entity. 

    So in the digital age, interaction is a kind of information processing between two actors, as one of the entities gives out the signal and the other one responds corresponding information, which their combination can give out a result to the whole system. Lev Manovich has mentioned that the principles of new media are gradually formed during the Industrial Revolution, which includes “modularity”  “variability”  and “automation” in his article Language of New Media. I think what he argues in his point of view is very direct and specific because media is one of the major carriers of interaction, the action of the sensor is the typical example of interaction, so the interaction can be presented even more representational.

A good example of interactivity:

This is a projection that can interact with the people who donate their two euros to this machine by using their credit cards, then the people will receive a certificate paper and also get the satisfaction of helping a starving or hiring kid. People give out the information of two euros and the machine will respond by printing a certificate, at the same time, the Charity organization can also use the donation to help some poor kids. This machine definitely carries out interaction with people who donated.

A not-so-good example:

This project is aesthetically amazing. I love their concepts and the installation. However, the projector just gives out the projection and doesn’t get any reaction back from the receiver, so it’s not an interaction art piece in the strict sense.
