A driver is a piece of software for your computer that interfaces to a hardware device, enabling the operating systems and other computer programs to access the hardware’s function without needing to know precise details of the hardware being used.
Drivers are hardware dependent and operating-system-specific.
Below are a list of useful drivers for Arduino-compatible boards.
