Burning Arduino Bootloader on ATMega328 using USBasp Programmer
https://www.electronics-lab.com/burning-the-bootloader-on-atmega328-using-usbasp-programmer/
In this tutorial, you’ll learn how to burn Arduino bootloader on a new ATmega328 using USBasp ISP programmer. Every Arduino Uno Board comes with a microcontroller called the Atemga328P, and they are already pre-program with Arduino Bootloader firmware. Therefore, there is no need to burn Arduino bootloader into those Atmega328P chips again. Here, we will […]
