I made this sound and light theremin following the Arduino Theremin instructions in the booklet. I used recycled materials from my house including a small cardboard box that housed nut cheese and some magazine photos and tape. I had a bunch of leaves in a vase that were on their way out, and decided to use them to camouflage the inside of the box, the arduino and breadboard. It also creates a little bit of stability for them and making movement less inside the box, the piece is still pretty delicate. I placed it so it still looks wild, the only piece of the circuit that’s visible is the photoresistor. One of the leaves is acting like a lever to open and close the box, triggering the scale in Arduino. There’s a whole in the side of the box to connect USB from Arudino to computer. The photoresistor is triggering the Theremin in the Arduino.

This is the code I used:
int sensorValue;
int sensorLow = 1023;
int sensorHigh = 0;
const int ledPin = 13;

void setup() {
pinMode(ledPin,OUTPUT);
digitalWrite(ledPin, HIGH);
while (millis() sensorHigh){
sensorHigh = sensorValue;
}
if (sensorValue < sensorLow) {
sensorLow = sensorValue;
}

}
digitalWrite(ledPin, LOW);
}

void loop() {
sensorValue = analogRead(A0);
int pitch =
map(sensorValue,sensorLow,sensorHigh, 50, 4000);
tone(8,pitch,20);
delay(10);
}

When I first set up the circuit board and wrote the code, the first note didn’t play, I tried switching out a button but that didn’t make a difference. Then I unplugged the wire going into the button and the other buttons were still playing notes so I figured maybe that wire needed to be switched out, I think even though it clicked in on both sides, it was a touch too short. Once I put a new wire in, the 1st button started playing.

At first there were code errors, I eventually realized that there multiple curly brackets at the end of the code, when I erased them, it ran smoothly.

Public Interactive Tech: Link NYC, various locations, observed 14th st & 5th ave.

The kiosk has a clean and simple interface. It’s free to use which adds to how people interact with it. There’s something about people having private conversations in public that I think I will always find somewhat odd no matter how used to it I become. With a bigger screen, it seems more toy-like and “futuristic” than the familiar iphone conversation spillage. It’s interesting to look into how fast people get angry or frustrated with a piece of technology since there is no consequence for it or response, although it can lead to less success. I observed some people becoming annoyed at difficulty connecting. Others that were connected and speaking loudly on speaker phone without earbuds which was sweet and funny.

LAB: ANALOG IN AND DIGITAL IN & OUT

For the analog input circuit I used a potentiometer and LED and programmed Arduino where the brightness of LED was divided by 4 that allowed the light to dim by turning the potentiometer. For the digital in /out I set up 2 LED light bulbs, I used a program with a conditional that allowed one light bulb to be on without pressing the button, that turned off when button was pressed and the other lit up.

I built upon the 1st assignment, making the eyeballs and mouth melt across and down the canvas. I wrote a sun to run randomly and change everytime the script ran. When the mouse moved one of the eyeballs trails across x and y axis with the background not refreshing. When the mouse is clicked the background, nose and mouth change color and the trailing eyes reset. I most likely have some lines in the code that aren’t doing anything as well.

Things went pretty smoothly with these labs. In the first lab I soldered a female dc and powered the breadboard directly using a voltage stabilizer and a 580 resistor with an LED. I then added a button switch to the circuit for on/off function. 

I then connected the breadboard and Arduino Uno with an LED circuit, using the same resistor and used the USB for power and to communicate with the laptop. I ran the code in the Arduino software to make the LED blink.

Screen Drawing

Once I got a hang of the x,y axis, height/width, color functions it was pretty satisfying and user friendly. I made a symmetrical face comprising of 3 eyes, based off of a drawing I did when I was younger. The middle eye is dripping down, a little break from the symmetry and an allusion to motion. I did a mixture of measuring the units and eyeballing (lol) for placement. I’m looking forward to playing further with depth and color intensity.

My Interests & CM

My background is in music production, art & movement. I’d love to develop multimedia shows where sound, graphics and movement interact. I’ve been increasingly into exploring various healing modalities and rituals and would like to incorporate into my art more. I’m thinking of doing one type of show with a very small number of participants, where they are enveloped in a multi-sensory way with the lines of performance / spectator / show / ritual being blurred.
