We took adequate measures to ensure that we did no damage to humans, environment and equipment.
The high voltage (12v) delivered to the LEDs was isolated from the controller by using optoisolator. 
The photo resistors used for light sensors contain carcinogenic elements, hence we took care while handling them.

Ethical and Legal Issues:

We have conformed to the IEEE code of ethics. We have acknowledged the use of some part of code from following site: for wireless communication although we have changed it quite a bit. We also confirm that we have not borrowed code from any where else. 

We have taken adequate steps to ensure safety of equipment and humans and have disclosed all the possible hazards to the best of our knowledge.
we would like to confirm that the results listed by us are true and accurate and have also been forthcoming in listing the short comings of the project. We have also strived to improve the overall understanding of technology which can be seen from our write up.We have also taken steps to ensure that by reading the report one can easily understand the product and reproduce it.

One of the major concerns for us was to find out if there are any patents against the application we were making. To the best of our knowledge, no patent exists. we also believe that we are not infringing any intellectual property rights
We have also treated suggestions and criticism as constructive and have strived to meet their expectations. We have also not discriminated against any one and have always helped our class mates whenever any one has asked.

FCC regulations:
Since we have used wireless transmitter, we had to ensure that our design complies to FCC regulations. The FCC regulation for part 15 transmitters allows intermittant control signals. Our device transmitted the signal intermittently too and for control of LEDs hence we can confirm that the regulations were complied with.

We acknowledge the invaluable advice of Prof. Bruce Land, while making this project and during the lectures. We also would like to thank the TA’s Ninoshka Singh and Pavel Vasilev for their support.
