drawing machine recitation

Materials used for Steps 1 and 2

  • 1 * 42STH33-0404AC stepper motor
  • 1 * SN754410NE ic chip
  • 1 * power jack
  • 1 * 12 VDC power supply
  • 1 * Arduino kit and its contents

During this recitation, we had two steps, and the first step required independent working. For the first part of the process for making a drawing machine, I connected all the materials that are listed above that were essential to make the circuit, with the help given by the schematic diagram. The objective of the h-bridge in this circuit was for it to allow speed and direction control. The main purpose of the circuit was for the motor to make a revolution, which was done so by the given code.

The Process

After testing the code and confirming the circuit worked, I then added a potentiometer to allow myself to control the motor, rather than the computer doing so in a timely order. After, I needed to modify the code for the potentiometer to let it satisfy the stepper motor we were given, which was a 200 step motor. After modifying the code, the movement of the knob matched the rotation of the motor.

Materials used for Step 3 

  • 2 * Laser-cut short arms
  • 2 * Laser-cut long arms
  • 1* Laser-cut motor holder
  • 2 * 3D printed motor coupling
  • 5 * Paper Fasteners
  • 1 * Pen that fits the laser-cut mechanisms
  • Paper

After completing steps 2 and 3, I paired up with my partner to collaborate our circuits and create one drawing machine. We used all the materials listed above to create “mechanical arm” that held the marker, while it was connected to the motors. After adjusting the mechanical arm, we were able to turn the motors and draw using the machine. One minor problem we faced while creating the machine is that we adjusted the short and long arms the wrong way, which did not allow the motors to run smoothly with one another. After realizing the mistake we had made, we adjusted the arms to allow the motors to run smoothly work with another and make a successful drawing machine. 

Final Drawing

Question 1

One machine I would be interested in building is a toilet paper holder that alarms you before it runs out. This would require a sensor in order to sense the amount it has left in it. This object can be manipulated to look like an ordinary holder.

Question 2

One art installation that compares to the drawing machine that I made in class was Scratch Series by Shawn Decker. This installation portrays various rhythms by using microcomputer-governed motors. This relates to the drawing machine in a sense that the motors are working together to make something, and in the installation it was a rhythm, whereas in the drawing machine, it was a drawing.  The actuators that were used for his project allowed it to “pull the scratches back and forth” to reflect patterns, which was very impressive, in my opinion.

Interaction

In my perception, interaction is the connection between all the parties. The output is either triggered by a motion or action by the other party/parties. There is no set amount of interaction, as different circuits require different levels of interaction. Different forms of interaction including moving, speaking, and touching.

 

Interactive Projects

The project I disliked was “Encounter”, the suspiciously curious robots. The reason I do not like this project as much is because the level of interaction is very minimal. Also, it does not contribute to help anything, or it is not as entertaining as many other projects created. Although the technology used to create this project is impressive, it was not a project that intrigued me. On the other hand, one project that intrigued me and that I was interested in was the “Apparatum”. This project was focused on music and it showed how “it emits purely analog sound”. The interaction and process used in this project impressed me and conveys a greater level of interaction.

 

The Translator

The project my group and I came up with was the translator. Moving to China, and adjusting to our surroundings comes with many difficulties, and one great difficulty we realized we had was the language barrier. Thinking of a way to diminish this barrier, we introduced the idea of a translator. To make it more fashionable, and easier to carry it on you, we made it in the size of a watch. In order for the translator to work, one person would have to speak into their watch, while the translator recognizes the language and translates it to whatever language the other party has chosen. You can also hold up your phone against the watch, if you need help understanding someone over the phone. While living in a new country, with a whole new language, this would make it easier to communicate with others efficiently. Compared to the project “Apparatum”, this device also emits a noise, although it is not musical. The interaction occurs when one person speaks into the watch, while the watch translates the input.

Materials:

-Arduino board

-back board

-jumper cables

-3-axis analog accelerometer

-LED lights

-220 ohm resistors

 

The sensor that we chose to work with was the 3-axis analog accelerometer. We first connected the sensor by the jumper cables connected to ground, power, and an analog pin. Before adding an output, we confirmed the sensor worked on its own. To confirm this, we ran the code to the Arduino, and it proved it work because all three numbers were changing when moved another way. After confirming the sensor, we chose to add 2 LED lights as our outputs. In order to do this, we connected 220 ohm resistors to each LED and each light had to be connected back to the Arduino through jumper cables. We confirmed that out circuit moved because when we moved it from left to right, a value changed, and the same thing happened when we moved it in all directions. While one value changed, the others stayed constant. One mistake we made during this circuit is that we did not connect the LED lights in the right place on the backboard, which resulted in no change in the lights.

Question 1:

We intended to make LED lights that dimmed or got brighter every time they were moved from one side to another. This circuit may be used in games, to indicate if someone is moving in the right direction or not.

 

Question 2:

One aspect of my circuit that I use in my everyday life is the sensor. For example, whenever I walk into the convenience store, it plays a tune, only if it senses someone or the door opens. Another sensor that I use in my everyday life is the sink, because the sensors allow it to turn on once someone’s hand is there.

 

Question 3:

A code is similar to a recipe because if not exact or precise, it would not turn out how it should be. Although, at times it may work, it may not work to be as intended to.

 

Question 4:

The advance technology affects humans in various ways today. For example, one way that sensors affect us today is that it may prevent crimes in one way or another. When a sensor recognizes motion, it may play a sound, or even call someone right away. This conveys how today’s computers influences humans and our daily lives.

Circuit 1: Fade

Components:

-Arduino board

-LED light

-220 ohm resistor

-hook up wires

-breadboard

To begin creating the circuit, I connected the anode of the LED light to analog pin number 9 through a 220 ohm resistor, and later a hook up wire. The cathode of the LED light was connected to ground, through a hook up wire. Finally, I connected power to the backboard by using a hook up wire to derive the power of 5V. After uploading the code to the Arduino, I connected the Arduino board to my laptop for the code to enable the circuit.

Circuit 2: Tone Melody

Components:

-Arduino board

-speaker

-hook-up wires

For Circuit 2, I placed the speaker in the backboard, and connected one end of the speaker to digital pin number 8 and the other to ground. The code on Arduino allowed the speaker to play a tone melody.

Circuit 3:Simon Says

Components:

-speaker

-buttons

-220 ohm resistor

-LED lights

-10K resistor

-hook-up wires

For the last circuit, we chose to make a “Simon Says” circuit that allowed the players to be interactive with the circuit. The buttons were placed in the middle throughout the backboard, which were connected to the Arduino board through hook up wires. The LED lights were connected through 220 ohm resistors, which allowed the lights to get the right amount of power. The speaker was connected to 5V, which allowed it to make a noise every time the player either won or lost the game.

simon says

Question 1:

Throughout my daily life, I interact with various types of technology. For example, a light switch. The interaction consists of me pressing the button, and the light turning on as soon as I do. Another interactive technology that I use daily is the sensors that are at many places, including stores and the school. As soon as it senses someone coming near, it reacts by either making a noise or opening a door. In my opinion, interactive is when both sides plays a role to result in an action. In the case of a light switch, the person turning on the light switch has to do some kind of action to tell the light to turn on.

 

Question 2: I recognize the LED light as one of the components, because it conveys an output that depends on whatever input it has received.

 

Question 3: If I had 100000 LED lights at my disposal, I would create christmas lights that light up based on the beat of the song. It can be used to put outside of homes for a light show during the christmas season, or even other occasions.

 

Question 4:

The Figure shown in the article conveys how interaction can be shown in the slightest ways possible. It states how “just in the act of standing up, a person effortlessly reveals important details..” This portrays on how the slightest interactions can mean so many different things.

Door Bell

Components Used:

    • Speaker
    • Switch
    • Jumper cables
    • Capacitor
    • Back board
    • Power supply
    • Arcade Button

 

A speaker is used to exemplify the input and to portray if the circuit is working or not. The switch was used to portray all that we have done and to demonstrate what we have built. The jumper cables were used to supply power from one end to another. For example, one jumper cable was used from the voltage regulator to ground. Furthermore, we used the capacitor to store energy from power to ground. All of this was conveyed on a backboard, which is an essential part of this circuit. The last part of this process was to plug it into a power source, that included our soldered cables. The first time we tried running the circuit it didn’t work due to the face that the jumper cable was not attached at the right parts. After all, we realized that it had to be connected to ground and our circuit was successful.door bell 

 

Lamp

Components Used:

  • Backboard
  • Jumper Cables
  • Capacitor
  • Resistor
  • Voltage regulator
  • Push button
  • Power supply

 

After completing the doorbell, we later started working on a circuit that would lead power to the LED and it would light up successfully. One component that was essential to this circuit was a resistor, in order to supply the right amount of power to the LED so we would not burn it. We used jumper cables to lead power from the power source, to the voltage resistor, through the resistor, finally leading the LED. We placed the switch in the middle of the backboard to demonstrate the process. Once plugged into a power source, our circuit was successful.

Dimming Lamp

Components Used:

  • Backboard
  • Jumper Cables
  • Capacitor
  • Resistor
  • Voltage regulator
  • Push button
  • Power supply
  • Variable resistor

 

In order to make the lamp more interactive, we later continued to make a dimmable lamp circuit. In order to control the LED to be dim, we had to include a variable resistor. This variable resistor needed to be on the same line as the LED, due to the fact that the LED was the object being controlled. One mistake that occurred during this circuit was that we put the variable resistor in the wrong place, which stopped us from being able to dim the light. Dimming Lamp 

 

Question 1:

After reading the “The Art of Interactive Design”, the circuits that we made during recitation 1 were not interactive, and if they were, they were at a very low point. It was mostly a one way interaction, with us inputting what the backboard exemplified.

 

Question 2:

In order to make “interactive art”, I believe that we can use our knowledge on creating something that involves multiple interactions, and makes the user involved in what they are doing. As explained in the reading earlier, the interactive art should include the users to listen, think, and speak.
