| The LCD and MPU6050 share the I2C bus on PC4 and PC5. The keypad uses eight GPIO pins, including PC0-PC3 as digital inputs. The buzzer and servo use PWM-capable pins, while the RGB LED uses three separate outputs. The project is powered through the Micro USB connector from a USB power bank, and all modules share the same ground. | The LCD and MPU6050 share the I2C bus on PC4 and PC5.
