FLOW CUE

PROJECT INTELLIGENCE

Fall 2025 - 5 weeks

The goal of this project was to identify an everyday problem and create a solution.

I created FlowCue, a shower light designed to keep you on schedule.

For this project I was to use an Arduino Circuit Board and sensors.

RESEARCH + INSPIRATION

2D EXPLORATION

I wanted to design a light that also works as a timer. This way not only does this light keep you on schedule, but also provides a shower experience. I experimented with the idea of a wall mounted light, or building the light around the shower head. After these initial sketches I decided to roll with wall mounted due to versatility and aesthetics.

ITERATIONS

FLOWCHART + STORYBOARD

I decided on using a PIR motion sensor and a duration knob for my shower light. Once the user enters the shower the sensor activates the light. Based on a preset time the sections light up one by one until all are green. Once set amount of time has passed the light will flash red signaling it’s time to get out.

PROTOTYPING

Created a low fidelity model to visualize design three dimensionally. After creating this model I adjusted the size by making it thinner.

CAD

Creating a detailed final model in CAD, designing the internals of the product to comfortably fit all components.

BUILD PROCESS

The body of the final product was 3D printed and spray painted matte black. Then I laser cut frosted acrylic and used parchment paper to diffuse the LED strips. After that I soldered all the wires and powered the light with the Arduino Nano and a 9 volt battery. Lastly, I used two suction cups to mount to the shower wall.

HOW IT WORKS

Once motion is detected the sequence starts based on a preset duration. The duration can be adjusted to any time spanning from 1-30 minutes. If you decide to adjust the duration mid cycle the sequence will restart and adjust to the new duration. Videos are sped up for demonstration purposes.
