Project Idea:

I wanted to use the instrument that Gopika and I made for one of the earlier assignments in a creative way. Given that I had an instrument that people could play, I decided to make a project where people could choose a song that they wanted to hear, and then play that song on the instrument.

I had originally planned to have the only sound come from the Piezo buzzer, however the Professor told me about a program called Sforzando, which is a software which allows the sound of musical instruments to be played from a computer. I coded four songs that I wanted to be played from the computer in Processing, and connected that to Sforzando, allowing the songs to sound much better than if they had been played on the Piezo buzzer.

The serial communication happened between Processing and Arduino by lighting up LEDs depending on which note was being played in each song. These LEDs also lit up when a note was played on the instrument. The instrument itself used an Ultrasonic Distance Sensor, and had 10cm ranges that mapped on to a specific note, which would then be played from the Piezo buzzer.

Reflections:

There were some aspects of the project that I wish I could have improved, but either didn’t have the time or the knowledge to.

The first is that I would have requested to use speakers, rather than my computer speakers. I hadn’t taken into account that the ambient noise of the show would drown out even the loudest volume on my computer, which had always been too loud in tests. The result was that it could be hard to pick out the melody that was being played from the computer.

I wanted to play instrument through Sforzando rather than the Piezo buzzer, as the buzzer doesn’t sound as good and was quieter than the computer speakers. Unfortunately, despite spending hours trying to figure it out, I just couldn’t get this type of serial communication to work in this direction. I had to settle for the buzzer in order to finish the rest of the project in time for the show.

The last major improvement would have been to have multiple octaves, rather than just one. Unfortunately this would have required more space and would have been inconvenient to play, so I settled on just the one octave. I also couldn’t add flat or sharp notes, as I had a limited amount of space and decreasing the distance that counts as a note below about 10 cm makes the instrument much harder to play.

So, I changed my mind about which idea to pursue for my final project. I decided to use the instrument Gopika and I made a few weeks ago, and have users mimic a snippet of a song that was played by using the instrument.

Unfortunately I wasn’t able to complete user testing yet, however I have someone lined up after class, and I will update this post with their feedback.

The professor suggested that I use Sforzando and Processing to play the songs, so that they sound better than the buzzer on an Arduino board, and so that is what I will be doing this class.

However, I have a working version that uses the Piezo buzzer on the Arduino, which plays a section of Ode to Joy, which the user than then mimic by playing the instrument themselves.

identify what you think will be hardest to complete, and start building it. Post the final idea, material/space needs, group/solo arrangement, and your progress on the project so far.

Idea:

I have committed to the screaming plane simulator as my final project idea, which will be a solo project.

Materials:

I have decided to not use the Orientation Sensor, and instead have the project be a 2D simulation, with pitch controlled from the Arduino. I will need a slider analog input for controlling pitch. I believe that everything else I will need is in the Arduino boxes we already have.

Challenges:

I haven’t made anything with a sprite sheet yet, and in my searches so far I have not found any sprite sheets of airplanes that are what I am looking for. Either I will have to create my own sprite sheet, or look much harder. I also haven’t used my computer microphone for anything yet, and so figuring out how to take in that input will be something I will need to learn.

Work So Far:

So far I have worked out what mechanisms I want to be present in my simulator (ie takeoff from an airport, landing in another airport, a progress bar, high scores, time-reducing tokens, obstacles to be avoided, and sound input to increase speed). I have an early version of my train simulator code from when I had planned to make a version of the Chrome Dino Game which I believe will be useful as a starting point for the Plane Simulator Code.

Idea #1: Music Mimicry

This idea is built on the instrument that we created for last weeks assignment. First, a short section of a famous song be played on the buzzer. Then, the player would have to replicate that short section of song by playing the instrument. If they play accurately, they win, but if they play inaccurately, they lose.

Input:

• Multiple (at least two) ultrasonic distance sensors
• Buttons: (1 on/off button, 1 play sound button, 1 accept input button)

Output:

• 1 buzzer
• Multiple LEDs (1 LED per note, to give some visual representation of the sounds being played.

Idea #2: Plane Simulator

This idea involves using an Adafruit BNO055 Absolute Orientation Sensor, or an analog sound sensor. Players would use the orientation/sound sensor to control an airplane avatar on screen. For example, yelling loudly would make the plane go faster. The game itself would be a side-scrolling course, with time to complete the course being recorded, and collectible objectives that lower the total time at the finish line. If you completed the course in 48 seconds but collected 5 tokens that each take off 2 seconds (for example), your final score is 38. Top scores would be recorded on a leaderboard so players could see how they stack up to others.

Input:

• Adafruit BNO055 Absolute Orientation Sensor AND/OR Analog Sound Sensor

Output:

• Visuals on computer screen

Video:

 

Inspiration:

Gopika was inspired by this  video of a Coldplay performance, in which it appears like the band is playing music on lasers in the air. We decided we would try to make an “air guitar” in a similar style. We would use six ultrasonic distance sensors that acted like “strings” and buttons that acted like the frets on a guitar. However because ultrasonic distance sensors need a clock, and each Arduino board only has three, we were limited to how many distance sensors we could use. We ended up with two distance sensors, each controlled by two buttons.

Process:

We first built a circuit with the ultrasonic distance sensor to see what kind of ranges were measurable. Next, we added a buzzer to the circuit, and wrote code to play a note whenever a given distance was triggered. For example, between 0 and 60 cm, every 10 cm corresponds to one note.

We added control buttons to the circuit next, one of which turns the system on (starts detecting distance) and the other changes the octave. Each code had two arrays of notes, each a full octave, giving the buzzer access to two full octaves of notes. If the button is pressed, the higher octave is played, if the button is not pressed, the lower octave is played.

Challenges:

We had a lot of trouble wiring the buttons into the circuit. At first, they didn’t work at all, and pressing the button wasn’t even being detected. Next, the press would be detected, but it would lag the system so that no tone was played for a few seconds. Finally Gopika realized that we had wired the circuit incorrectly and the buttons finally worked.

Final Work:

See if you recognize the song:

And with the octave change:

Inspiration:

I struggled to think of something creative to make, but I eventually settled on a kind of game where a red, a green, and a blue LED would light up, each with a random brightness, and then the player would have to use a potentiometer to control the brightnesses of each of the three LEDs in order to match the random brightness that they had. If the player was within a certain range, a green LED would light up, signifying that the player was correct, otherwise a red LED would light up signifying that the player was too far off.

Process:

I used some of the code from the Maintain State circuit we built, along with some from the Analog LED circuit from class as well.

Challenges:

My idea was quite complicated, especially for someone new at coding like me, and I spent too long trying to work it out. I eventually realized that I could have the same process with a blue LED that the player would control, which would make the circuit much simpler. I simplified my code and rebuilt my circuit, although for some reason, I encountered the same problem I had before, which was that all three LEDs would light up, and neither the button nor the potentiometer would change that.

I tinkered a little more, and the video shows as far as I got, however because I spent so much time on the more complicated version of this idea, I did not have enough time to completely troubleshoot either the code or the circuit. I had initially thought for a long time that the problem must have been somewhere in the code, but I think now that it might be in the circuit.

Final Work:

Diagram of my circuit on TinkerCAD

Code:

//potentiometer
const int knob = A0;
//target blue LED
const int bled = 5;
//incorrect and correct LEDs
const int iled = 9;
const int cled = 10;
//blue button
const int bbutton = 2;
//on/off button
const int obutton = 12;

bool bledOn = false;
bool iledOn = false;
bool cledOn = false;

//on off button
bool oButtonOnOff = false;
bool oButtonPrevOnOff = LOW;

//blue button
bool bButtonOnOff = false;
bool bButtonPrevOnOff = LOW;

void setup() {
  // put your setup code here, to run once:

  Serial.begin(9600);
  pinMode(bled, OUTPUT);
  pinMode(iled, OUTPUT);
  pinMode(cled, OUTPUT);
  pinMode(bbutton, INPUT);
  pinMode(obutton, INPUT);

}

void loop() {
//turning the LED on and off with the BLACK button
  bool oButtonCurrentState = digitalRead(obutton);
  int randomLED = random(255);
  if(oButtonCurrentState == HIGH && oButtonCurrentState != oButtonPrevOnOff){
    digitalWrite(bled, randomLED);
  }
  oButtonPrevOnOff = oButtonCurrentState;
  bledOn = !bledOn;

//turning the LED on and off with the BLUE button
  bool bButtonCurrentState = digitalRead(bbutton);
  if(bButtonCurrentState == HIGH && bButtonCurrentState != bButtonPrevOnOff){
    digitalWrite(bled, 255);
  }
  bButtonPrevOnOff = bButtonCurrentState;
  bledOn = true;
  
  int knobValue = analogRead(knob);
  //fix high and low based on potentiometer
  int mappedValue = map(knobValue, 850, 350, 0, 255);
  int constrainedValue = constrain(mappedValue, 0, 255);

  digitalRead(bled);
  if(bled == HIGH && bButtonPrevOnOff == HIGH){
    analogRead(knob);
    analogWrite(bled, constrainedValue);
  }

  int bledValue = analogRead(bled);
  if(bButtonCurrentState == HIGH &&  (randomLED - 5) < (bledValue) < (randomLED + 5)){
    bool cledOn = !cledOn;
  }
  if(bButtonCurrentState == LOW &&  (bledValue) < (randomLED - 5) || (randomLED + 5) < (bledValue)){
    iledOn = !iledOn;
  }
}

 

Introduction:

I am obsessed with privacy. My dorm is my safe haven from the pressure of school work and socializing, so I am obviously annoyed when that peace is disturbed. It is from this that I had the idea of a Do-Not-Disturb button. An automatic version of the signs you hang on hotel room doors, to signal to roommates and visitors that I am not to be disturbed.

Procedure:

My initial idea was to have a simple circuit like we built last week. When I close my door, the circuit is closed, and if I pushed a button, a red LED would light up, and maintain state after the button was pushed. If I pushed it again, the LED would turn off, signaling that I am available. If my door was open, then the light would be off, as the circuit was broken.

However, in order to make this more hands-free, the Professor suggested that I use some other signal besides a push button to indicate that I was not to be disturbed. He suggested that I put conductive material on my pillow and the bed below the pillow, so when I was asleep the circuit would close and the light would come on. The circuit itself is very simple. I made a diagram of it in tinkerCAD, and attached a screenshot here.

The small breadboard off to the side represents the conductive material attached to the pillow. (I don’t know how to put conductive material in tinkerCAD). In this diagram, the circuit is closed. The code for this is also quite simple, with the Arduino reading the state of the “pillowPin” and writing that to the LED pin.

The procedure is relatively simple. When the conductive material on the bed and the pillow comes into contact, the circuit is closed.

When the circuit is closed, the Arduino will read the current state of the LED pin and change it. (The LED is always off to start). When the circuit is broken, the LED will turn off.

Demonstration:

https://youtu.be/ujdsTZ9_EqY

const int ledPin = 3;
const int pillowPin = 2;

bool sleepWake = LOW;

void setup() {
  // put your setup code here, to run once:
  pinMode(ledPin, OUTPUT);
  pinMode(pillowPin, INPUT);

}

void loop() {
  // put your main code here, to run repeatedly:
  bool currentState = digitalRead(pillowPin);
  if(currentState == HIGH){
    sleepWake = !sleepWake;
  }

}

Inspiration:

I really like trains, so I wanted my game to represent that aspect of my interests. I was inspired by the Dino game on Google Chrome, as that had similar characteristics.

Process:

I basically tried to brute force this entire code. I found a video of someone who made their own version of the Dino game from Google, from which I drew some inspiration.

I have five classes: Ground, Tree, Obstacle, Player, and Station.

The ground is simply a line that acts as the rail, and has regularly appearing lines underneath which represent the ties of the track.

The obstacles are now only the red signals, but it used to have the green signals and stations. There is a boolean for SPAD (Signal Passed at Danger) which triggers a fail if you pass a red signal too quickly.

The trees now include the green signals, as the trees and green signals are all passive background objects.

The player always stays in the same spot and “controls” the train. They are really controlling the speed at which the objects move across the background. The W and S keys control the speed.

The station has a green rectangle underneath the image that is suppose to denote the stopping zone, however the station no longer loads and I don’t know why.

Final work:

Challenges:

I had lots of challenges. If you had seen my midterm progress post, you can tell how different the two versions are. The biggest two issues are that the game will fail seemingly for no reason, and the station apparently never shows up. I think that is because the green signals and station both used to be a part of obstacles, there is some vestige that no longer appears on screen, but still fails. I also tried to get the station to load only after a certain amount of time, but once it was moved to its own class, it stopped working.

If you keep your speed under 3 km/h, you won’t fail, but also the station will never appear. Because I was attempting to fix this issue, I didn’t have time to add sound.

Inspiration:

I really like trains, and so I thought I could try to make a basic train simulator in Processing. I wanted the user to control a subway train between two stations, have to navigate a red signal, and stop and the next station without overshooting the platform. I also wanted the background to be populated with other NPC trains.

Process:

I started by trying to build the background for the simulator, which would simply be a top-down view of the tracks and tunnel. I made a platform, two rails for the tracks, and made a class for trains. I tried to add a .png image for the tracks, but for some reason, it wouldn’t load in. I never got an error message, I simply couldn’t see the image. As a place-holder, I added some rectangles for the rails. You can’t control the train yet, but the goal is to be able to.

Final Work:

Challenges:

I had a lot of challenges so far. For some reason, the rectangle of the subway train stays on the screen without disappearing. As mentioned above, I can’t load the tracks .png file, and finally I haven’t yet added user control over the train.
