This hex file is called the Arduino Bootloader. hex file which can be installed on AVR chips that allow you to program the board over a serial port, ensuring all that is needed to program a microcontroller (after installing the hex file) is a serial connection between the microcontroller and the Computer which can be achieved using a USB to UART adapter. It’s not beginner friendly, thus to eradicate these issues, Arduino created a. hex files, not to mention the huge knowledge of the C programming language required to write the code.

Programming microcontrollers can be a bit tricky, as they require special programmers and.
