The rise of multi-tasking and the increasing demand for seamless user experiences have led to a need for more intuitive and efficient ways to manage information. While traditional methods like pop-up windows or notifications can be disruptive, a dedicated display offering real-time metrics could provide a more discreet and focused approach to managing relevant data.

Current solutions for displaying metrics during active tasks often interrupt the user's workflow. This can be particularly detrimental in activities requiring focus and precision, such as gaming. There is a lack of a dedicated, non-intrusive display solution that can present relevant metrics without requiring users to switch between applications or lose their current focus. This project aims to address this gap by developing an IoT system that utilizes an LCD screen to provide a continuous stream of metrics without disrupting the user's primary activity.

The circuit diagram showcases a basic setup for the ESP8266 microcontroller, connected to an I2C LCD display and a joystick. The ESP32, a powerful and versatile microcontroller, serves as the central processing unit for the system. It's connected to the LCD display via a set of wires, for 5V, GND, SDA, and SCL. The ESP32 is also connected to the joystick via a set of wires: 3.3V, GND, VRx (analog), SW (digital).

The Pinout scheme of the ESP8266 board that I used is the following:
