Mobile app for controlling LED panels

Polyscale company

This project case was developed for Polyscale, a company of approximately 50 employees operating in the appliance, electrical, and electronics manufacturing industries. The department we collaborated with specialized in developing, manufacturing, and distributing light guide plate (LGP) based systems.

Conceptualizing solutions based on microstructures-taking into account constructive, optical, and design-related dependencies.

Optical layout, simulation, and optimization according to the set goals.

Manufacturing of micro-tools.

Prototyping and evaluation of their effectiveness.

Transition to mass production and production through pressure casting.

Development of corresponding LED solutions.

Client story

Our client was completing the production of LED panels and needed to develop a mobile application for controlling these panels. The interesting part of the task was that it was essentially a constructor, where the end user could determine the order of the panels by composing different geometric shapes.

During the requirements gathering stage, the client noted that speed was important to him at the moment, as the company had to present its project at an exhibition.

One of the project’s difficulties was that we did not have any LED panels manufactured at the time, so we had to use the Bluetooth module HC-06 to successfully test the application.

The first version of the mobile application provided data transmission via Bluetooth Classic connection, while the second version allowed for data transmission via BLE.

Our solution

Taking into account one of the client’s most important criteria – time, we decided to purchase a ready-made template that already had UI elements.

UI elements

How does it work

We involved one of our top designers, who took into account our client’s wishes and made changes. This step allowed the client to have a clear vision of the product even before the code was written. It also allowed us to move more qualitatively to the next stage (task estimation) as we clearly understood what we had to do. After the estimate was approved, we proceeded with development.

Results

We developed a mobile application that could be downloaded using Firebase.

We tested its functionality using the Bluetooth module HC-06.

After sharing the code, the client was able to connect the application to an LED panel.

We made several small hotfixes while in online mode.

We supported the project throughout its demonstration at the exhibition.

We received excellent feedback
from the client.
