 ## Hardware
 
 The project is built around an STM32 microcontroller and includes multiple input and output components to create an interactive lighting system. The power supply is based on two 18650 Li-ion batteries, connected through a boost converter to provide 12V for the LEDs and a step-down regulator to supply 5V to the microcontroller and other components.
 STM32 Nucleo board – main controller
 RGB LEDs – main light source
-MOSFET transistors (IRF1405) – used to control LED channels
+MOSFET transistors (IRF1405) – used to control LED channels!!
 Potentiometers (x4) – color and brightness control
 Capacitive touch sensor (TTP223) – mode switching
