After hours of boring Zoom calls, I decided that I needed a way to make online education more exciting and colorful.
What it does
CircumLumen uses an online webserver to rotate a color wheel to change the color of desk lights. The CircumLumen can change the lights to red, blue purple, and yellow. This device not only makes online learning more bearable, the changing of light color can often help improve focus and productivity.
How we built it
I used the esp32 to create a webserver which ran on my wifi network which allowed me to control the output of the esp on a website on the computer. The website sends a signal to the esp which is received by the arduino which then uses a L293D to drive the motor to turn the color wheel. Both the arduino and the esp were powered using a 9V battery.
Challenges we ran into
I had trouble driving the motor with the esp32, so I decided to instead use the esp32 to give signal to an Arduino, which I was more familiar with. Mounting the color sheets to the motor, and the motor and electronics to the lamp itself was also quite challenging.
Accomplishments that we're proud of
I am proud of finishing my first IdeaHacks project and creating something which I can and will actually use!
What we learned
I learned how to use an H bridge to drive a dc motor and how to create a webserver to control a microcontroller through wifi.
