Hullo Bro ,
How are u? , Hope all is good !
Regarding your project , I have worked on many Arduino-based projects that included IOs , LCDs , Buzzers and many other peripherals . Regarding the USB interface I could show you sample of my previous work on my youtube channel and could also recommend more than one option for USB interface. I have all required HW and I 'm always before time.

I have long experience with 8-bit , 16-bit and 32-bit micro-controllers. I work with Microchip (PIC) , Atmel (AVR , SAM) , ST (STM) , TI (MSP) and NXP (LPC) micro-controllers. I use KEIL IDE , Atmel Studio , Code Composer Studio and MPLABX IDE . I deliver tested , neat and well-commented code that can be reused or modified for future development.
More to be discussed once you contact me .
BR,
