The goal and description of this project:
instruction for wireless assignment is to choose one of the wireless topics covered in class and put it to practice for use in everyday life. I chose IR Remote control as the topic I want to explore. I tried to use the remote control to control the two LEDs.
Components list:

in this project, I wanted to explore 2 components that I had in my Arduino kit but never used: the Bluetooth shield + RGB Led.

Goal: The goal of this week’s wireless assignment is to be able to control a RGB mood light via smartphone blue tooth.
Core Components:
Assembly:
RGB LED to Arduino:
Blue Tooth Connection to Arduino:
How it works: As the concept goes, via bluetooth and the correct smartphone app I will be able to control the color of the LED wirelessly. The designer of this project went into depth about the logistics of how the RGB LED actually changes colors by describing how the Arduino uses a digital representing Analog signal that varies pulse to mimic a PWM (Pulse Width Modulation). By using a digital representing Analog signal the colors are able to seem like they are gradually changing even when they are not.
Problems: I faced a plethora of problems with this assignment. From jumping to project to project trying to find a source that didn’t rely on Android applications or Google Play to simply the code refusing to upload onto the Arduino “programmer not responding.” To say the least I had many difficulties. Though I believe the most prevalent can be found in the fact the alternative applications I downloaded onto my phone (Iphone) to control the LED via blue tooth could not connect. I’m not sure if it was because of the code/ Arduino blue tooth or the app not being compatible with the program, regardless it didn’t work. I ended up accidentally burning out my RGB LED, so I will try again tomorrow with another application!
