Introduction

• Statement of Purpose

Have you ever wanted to own a cool decorative appliance at your dorm to show it off to your friends? The goal of our project is to propose a color-changing LED lamp that automatically adjusts its brightness in response to the change in light density. We plan to create a lamp that can be switched on and off in multiple ways, including remote control by a smartphone app, a manual switch, and a sound-control system, which would differentiate our lamp from similar products

• Background Research

We plan to construct the lamp using an LED ring, a giant mechanical keyboard switch, and a 3D printed base support. We can apply a photoresistor to modulate its response to the change in light density. We need to use a bluetooth module to realize the remote control function. A tutorial of this could be found in the video below. The sound-control function may be realized by an Arduino program. We choose to do this project because prior to this proposal, we have made an LED lamp that changes colors in gradients when it is connected to power, but we want to add more features to refine the design of the lamp. The project will significantly improve home decoration.

Design Details

The block demonstrates the work process of Avalon Lamp. Avalon lamp is a smart lamp. The users can have three ways to control the light. The first way is to manually turn on the light. The second way and the third way depend on the sound and light intensity. If the sound is loud enough, the sound sensor would decrease the resistance to allow the flow of electrons; if the light intensity is big enough, the Photoresistor would decrease the resistance to allow the flow of electrons. Through this approach, the Arduino IDE based Pro Micro would detect the flow of current controlled by the sound and light sensor and activite the lamp. In addition, the Arduino would also be programmed to have algorithms to determine the color pattern of the ring of LEDs in the lamp.

Parts

Inside part:

• A sound sensor

• A ring

• LED with different colors

• Pro micro

• Wires

• Tools for welding

• A photoresistor

• Bluetooth module

• Volatage source 

• Breadboard

Possible Challenges

• The programming for the controlling of color and sound, we have the basic knowledge for simple code, but it may not be enough for some functions and designing

• The electronic parts for pro micro and circuit boards, which will somehow hinder us on sensors

• The cading of small parts for the construction of our lamp, the size and material are both important for a component to work

• The processing of sound control with words recgnization
