Surya is a toy, who needs love, affection and the Sun to survive. In today’s world of video games, a child needs a companion who would play with her outside or encourage being outdoors. Sun is a source of health and vitality which every child could benefit from. Get Surya for your kid and let both of them enjoy the sun together 
11/21 – Timer circuit with arduino, get PV cells, communicate readings back to computer via bluetooth?
11/28 – PV cells to work with timer, Design of sunny plush
12/5 – making all of them work together, sunny plush v 2.0, webpage with readings from sunny
12/12 – packaging and presentation
Sunny is a buddy you can carry around who breathes sunlight, he needs his dose of sun everyday. He hangs out with you in your key chain or in your backpack. So, if you go out in the sun he goes out too.
You can check how sunny is doing today by pressing his head, if he has had enough sun he glows green, if he is ok he glows pink, he is blue if he hasn’t had enough to breathe 
An upgraded version of sunny can dream and save the amount of time spent in the sun onto the computer when he sleeps in is green pot-bed.

I changed my LEDs to super brights and corrected the jitter that my code had by using the technique that Matt was using so the code is very similar to his.

Currently, it plays three songs and forwards every time it detects a presence

Code
I started off with Matt’s code for the range finder–
#define NUMREADINGS 10
int readings[NUMREADINGS]; // the readings from the analog input
int index = 0; // the index of the current reading
int total = 0; // the running total
int average = 0; // the average
int play = 9; // which light connected to digital pin 9
// int stop = 10;
int fwd = 11;
int pValue = 0; // variable to keep the actual value
// int sValue = 1; // variable to keep the actual value
int fValue = 1; // variable to keep the actual value
int rangeFinder = 5;
int closeValue = 0;
void setup()
{
Serial.begin(9600); // setup serial
for (int i = 0; i < NUMREADINGS; i++)
readings[i] = 0; // initialize all the readings to 0
}
void loop() {
/* total -= readings[index]; // subtract the last reading
readings[index] =analogRead(rangeFinder) ; // read from the sensor
total += readings[index]; // add the reading to the total
index = (index + 1); // advance to the next index
if (index >= NUMREADINGS) // if we’re at the end of the array…
index = 0; // …wrap around to the beginning
average = total / NUMREADINGS; // calculate the average
// send it to the computer (as ASCII digits)
closeValue = average;
*/
Serial.println(analogRead(rangeFinder));
if(analogRead(rangeFinder) > 300) {
// pValue = 1;
// sValue = 1;
fValue = 0;
pValue = 1;
}
else{
fValue = 1;
pValue = 0;
}
analogWrite(play, pValue);
// analogWrite(stop, sValue);
analogWrite(fwd, fValue);
/* Serial.println("—-");
Serial.println(pValue);
Serial.println(sValue);
Serial.println(fValue);
Serial.println("—-");*/
}
Finally I got the winbond chip to work. The problem was that I was not grounding FT

For my thesis, I am looking at urban spaces and researching on how people navigate through the space and communicate within that space.
For my midterm, I would like to make a toy which will communicate whether you are intruding its space by sound and light feedback. The data will be collected from surveying 3 different cities, New York, Madras and Amsterdam. There will be three robots made with different IR ranges depending on the results of the survey.
This will act as a tool that expresses how physical contact, personal space and such differs according to the geographic location and culture.

Fav. Childhood toy – pull string toys that wind n’ make music sometimes roll eyes n’ stick out their tongues. My sister had one on her crib when she was a baby.. I used to spend ridiculous amount of time on it. I m not really sure what caught my attention cos they keep pretty much repeating the same thing over n over again.
My background is in elec. engineering n’ programming but it has been a while since I dealt with circuits. I would like to use this class to dust the cobwebs in my head. Also, I see it as an opportunity to prototype for thesis.
I took apart a toy – cowboy on a rocking horse. I was interested in finding out how the rocking movement was achieved. To take it apart, I had to remove many screws and the toy also played music along with multiple blinking LEDS. After removing all the plastic. I reached the gears which made the movement possible. A servomotor controlled the gears which made the horse Rock.
