Developing the second version of the device, which included two key improvements – in addition to the microcomputer, also using a microcontroller, which controls the operating parameters of the sensitive computer. The system monitors, among other things, the temperature, humidity, but also continuity of power supply, being able to safely turn off the computer in case of a power outage and temporary usage of the battery. The second improvement was replacing the RGB diode with 5 LED panels, which makes it possible to display animations during positive and negative scanning, as well as in an idle state.
