Here's our first update from yesterday! As all of us have very little experience with Arduino and its parts, our first goal was to attempt to connect out bluetooth modules to the Arduino board and attempt to switch on and off an LED from our mobile phone. Watch video: http://sendvid.com/mufr8kse

Later on the 16th, we connected the Arduino speaker to our breadboard using tutorials online. We then found a sample hard-coded song we could use to test our speaker as well as form the base for sound production. Watch video: http://sendvid.com/gi8dds3h

Then, we connected the RGB sensor to the breadboard. Initially, the sensor refused to work and we believed it might be due to a loose connection. After a short trip to solder the sensor to its pins, we tested the color sensor, and it could now output the RGB values of the colors it sensed. Since in our final project we need to sense the emission of red light and not just red in general, we then switched off the white LED emission from the sensor.

The last milestone we hoped to cross yesterday was renaming the slave bluetooth modules on each of our arduino boards. Unfortunately, after about an hour of coding, though our serial monitor registered that our bluetooth name had been changed, the changes weren't reflected on the phone. We decided to handle this problem later.

Today, we're focusing on making the parts work together. Our first goal was to make the LED on the breadboard respond to another lit LED being brought close to the RGB sensor. Watch video: http://sendvid.com/edz083fd

Next, we linked the speaker to the LED. When a lit LED is brought close to the RGB sensor, the LED on the breadboard turns on, and the speaker emits a certain pitch. WHen the LED is removed, the LED on the breadboard turns off and the speaker emits a different pitch. Watch video: http://sendvid.com/c7ye6ng9
