In this thesis we describe the process of designing an interactive installation, the prototype development, and the placement of the final product in a gallery. Through the development of smaller prototypes, the possibility of using conductive paint for touch detection and the ability to control a light and sound subsystem was explored. The developed interactive installation consists of fifteen rings with LED strips, a bench that allows interaction through applications of conductive paint, and a sound module. Touch detection was realized using capacitive inputs on ESP32 microcontrollers. The variability of values on the capacitive inputs, which depends on several factors such as touch surface and environmental parameters, was addressed. Seventeen ESP32 microcontrollers were used in the system's implementation. The ESP-NOW protocol was used for communication between microcontrollers. We describe the software and hardware used in the system's implementation. Software for two main control systems and fifteen subsystems on the rings with LED strips, totaling 1006 LED elements, was developed in C++. Testing the system in the gallery space confirmed its reliability and also received positive feedback from gallery visitors.
