PROJECT SUMMARY
I was curious to know if a human action could trigger a robotic action, so I came up with a motion lamp, this project consists in waving your hand about 7m away from the lamp and having it to turn on. I discovered a lot about coding, and circuits while building this project.
WHY?
Are you the kind of person that keeps turning on the lights and forgetting to turn them off, this is the reason I made the motion lamp, this can help save electricity in many places , not only in homes but also streets, by installing sensors across the road so when a car moves by that one street light turns on, but as soon as it leaves the street light will turn off.
HOW?
I started thinking on how to save electricity, I finally settled on using motion to turn on or off a light. I built my project on tinkercad(a website allowing you to simulate projects) to make sure it works, and my LED’s don’t burn and my code works, I then bought my sensors, LED’s, and resistors on Amazon, then started assembling my circuit on my breadboard and arduino uno R3, then I bought some butter paper(translucent paper)to then wrap around the jar in witch I put my circuit and added a nice design on the outside.
WHAT?
My model consists in a breadboard setup with 7 LED's, and a PIR sensor, when the PIR sensor reads 1 then the LED's turn on, after the movement is detected, the LED's will stay on until the next movement is detected, thus creating a motion lamp.(pictures below)
SO WHAT?
These results show that energy could be saved in every day lives, you could also simply use it as a night light. I've learned a lot during this project such as how to control sensitivity levels from the PIR sensor, and how to value resistors to know witch are the right ones to use.
WHAT'S NEXT?
My project could be extended in numerous of ways such as putting PIR sensors in the front of your door so every time you walk into the room the lights will turn on, but when you walk out of the room the lights will turn off saving your electricity consumption, a similar example is street lights, every time a car passes by a street light it turns on and as soon as it leaves the street light turns off, then saving electricity.

REFERENCES & ACKNOWLEDGMENTS
I would like to thank my mom and dad for supplying me with the resources to make this project, I would also like to thank Tinkercad for providing me with a platform to build my simulation on.
JUDGES FEEDBACK
This is a fantastic project because of the motivation behind creating the lamp as well as your determination to create it. It is very thoughtful to consider methods in which you can save energy in a practical way while going through the motions of day-to-day life. You also seem to have profound skill in building 3D models as well as coding. I wonder if there could be an included setting where you can disable the motion feature if you wanted to keep the light on or off for extended periods of time.
