Mini Project 1

When originally looking at what I wanted my final project to be, I thought I would want the human interaction to involved touch of some sort.


So I tried out multiple pressure sensors. The project theme was signal and I wanted to get the signal to be from human interaction of some sort. After testing the pressure sensors I was exploring and found pulse sensors, I immediately had to try it out.

From touch to pulse I wanted the person to allow the signal to happen. I used a pressure sensor to turn an LED on and then I also used a pulse sensor and it communicated to processing, this was vital for my final project because it's when I realized that I could use some of the coding we learned in programming and put it to use (finally).

I had no idea what the sensors did. Ivette and I were exploring and testing things so here is the research that I had to do to figure out what I was working with exactly.

I had to follow a tutorial but it felt like some of the info was missing so I had to wing it:

Mini Project

On my previous post I stated my idea and how I was going to achieve that. Katerie alerted me that if I was to get arduino and processing to successful communicate and get some sort of hardware to aid in that handshake (my potentiometer) then that would be sufficient enough. My mini project is basically a smaller and more simplified version of what I intend to do for my final project, dealing with human interaction and synesthesia. Hope you guys enough:)

1. So ambitious, Dreezy! I love the pulse piece; it was successful for me and I think the idea of visualizing a pulse is very captivating. It's almost mesmerizing when you can feel your pulse under your fingers and see it at the same time. I think the pressure sensor is interesting too - I would love to see the two of these combined somehow. -Shimul
2. I really appreciate your struggle,  it was very good creativity that you choose the sensor worked with human part.I think your works have a grat potencies to have a forms.  Setter
3. It worked on mine, it was cool. When you put your finger in the strap th heart monitor and led beeps anti displays your heart rate. mine seemed to be too wild. 
4. I commend your effort for creating two mini projects. The blue LED touch sensor works perfectly but I'm not sure the heart monitor is working exactly right. It seems a little too sensitive and runs without a finger in it sometimes. BUT I applaud your ambition for making it and especially it working to any degree, especially since this is something I am looking forward to making myself for my final project. 
5. I think this concept is really cool. i never would've thought of incorporating the pressure sensor to make a heart monitor. It was really ambitious. Kinda sad you couldn't get the sound to work, but I understand your pain lol.
6. i like the green one better. I am really glad you experimented with visuals on a computer and in LED form and sound. I think you can defiantly expand more with the green one. 
7. Woah! The heart rate one is absolutely incredible! I love the little detail of the LED fading out instead of turning off and on, it really mimics a heart rate well. 
8. Very interesting! I can definitely see the amount of effort that went into the processing interface. The way that it works with the heart rate sensor is very successful! The pressure sensor is also successful, although I'm not sure what connects the two of them. Both seem to be working well so I can only assume that they'll be adding up to a bigger project. -jen
9. Maria - I'm not sure how sensitive the sensor for the finger is but for it's purpose it works really well. Along with the other sensor for the LED. Definitely ambitious, I can't wait until your next one.
10. Aaron - Nice job pairing audio with your LED light. I really respond to the tactility of the two different sensors. How might you go from here and edit the code to do something more or unexpected with the heart rate sensor? How could the touch sensor be embedded in another tactile activity? 
11. Kris- very well done, i especially love the pulse sensor. It makes me feel...vaguely anxious. The pressure sensing strip is neat too. where are you going to go with this? 
12. Tatyana- The pulse sensor is very cool, and something we haven't seen before; kudos on being innovative. I felt like i was at the doctor's. your other sketch, with the touch strip was very cool, with the use of pressure to make the light glow darker. 
13. Kelsey- it's freaking me out that it doesn't want to detect my heart rate even though I watched it work just fine for other people. I reminds me of this app my sister has that detects your heart rate by placing your finger on the flashlight of your phone. The app isn't accurate of course, but its fun to play with. And I feel the same with your project. 
14. I like the fact that this piece has audio as well as visuals, as well as the fact that there are 2 forms of interaction. I'm wondering how you made the program that visualizes the heartbeats and pulse? It would be interesting to have measure people's heartbeats while they are being asked questions

10/12 Mini Project Maria

Got the piezo to play a small piece of music. Based on a tutorial that used a MIDI file to turn notes into something that the Arduino can read and play.

Program a Simple Tune on an Arduino Uno

Press the RESET button to restart.

1. Maria, this is beautiful. I am impressed that you were able to program this to play an actual song! I am wondering, however, if there was some other component that you could have added to this -- maybe to alter the sound somehow? I think some interactivity would make this even better! -Shimul
2. Even though it's a piezo, it sounds natural and melodious; it would be interesting to have several going and harmonizing with each other, as well -Kayla
3. It works! This is really great and the song is definitely recognizable. It would be interesting if there were some sort of sensor so that the viewer interaction would be more than pressing the reset button. To have it trigger somehow could embed a layer of meaning that the current project lacks. -jen

Mini project1,

­­­­­­For first mini project, I would like to show the differences and similarities between two or more words in two different languages (Persian and English). This project is along with people interaction in which not only see the translation, but also they are part of that to disclose and show the concept. 

I have a plan for interacting and showing two words with same translation, specially some words that have same letters or sort of close pronunciation, it is better to use the different color LED or even same color. Two words are overlapping, and by moving the hand one word starts to light and with second movement the second word with LED light will be on. This process is like a gradually lighting with RGB LED. Simply at first all the common letters which are the top of the word is going to be on. For this project I think I use Proximity sensor or IR distance sensors. In this project I need a sensor, which detects motion or movement, and then the output is lighting the LED.

Parts for this project is mostly similar to parts in Chapter 4 in Exploring Arduino book
