For my final project, I am creating a piece of artificial moss wall art that has an interactive component. I plan to embed LED strips into vertical CNC milled grooves in a rectangular piece of wood I have. I will program the LED lights using the Arduino microcontroller so that when a person walks up to the installation a sensor triggers an LED sequence that mimics a waterfall behind the moss. In addition to the LED lights creating a waterfall effect I plan to incorporate a speaker to play water sounds to add to the overall experience. I chose this project because it uses a piece of material that I already have and I feel that it has the potential to be cool and beautiful.
For the use of LED lights, I am going to use four addressable LED strips and program them using the Arduino IDE with the Elegoo Arduino Microcontroller. I plan on purchasing either a wall power adapter or a battery pack for the Arduino since the LED lights will require too much power for it to be powered by a 9V battery. I will use the ultrasonic sensor included in our kits to turn on/off the light and sound sequence. I plan to use my computer speakers to play the sound.
The compelling purpose for my project:
The meaningful experience I am envisioning for the user is mainly the art installation itself but also the interactivity of it as well. I hope for the user to walk away with the wow effect and be impressed with the piece.

Graphic communication of the interactive system:
I also plan to incorporate some floral aspects into my moss art such as this however I don’t know exactly how I want to do it yet so I haven’t included those materials:

Week of April 10th: Gather Materials for the Project; Get the electronics programmed.
Week of April 17th: Get the lights physically installed in the installation and start getting the moss glued and laid out
Week of April 24th: Finishing touches to the installation/ getting the documentation finished
I really like the design of this project. It’s bringing nature to the inside. Are you planning to add any additional water feature besides the sound?
Hi, looks great so far! I would caution against increasing the length of the signal wire between the microcontroller and ultrasonic because this can induce noise in the system. Do you know if the art pieces you have used for inspiration use real or fake moss? Is there a reason you went with fake moss? I am interested in seeing the final product and what the light show looks like.
I’m so excited to see your project in action. Your tabulation of materials is really well organized, have you been able to get the materials yet?
