In this video I show you how to program your Arduino boards using USBasp programmer. In the video I connect an USBasp programmer to an Arduino board and using Arduino IDE I upload a sketch, but before I show you how to install drivers for the programmer on Windows 10. I also show you how to burn back the bootloader because without that you won’t be able to program your Arduino boards using USB. I also recommend you to upgrade your USBasp programmers to the latest firmware, see: https://youtu.be/1tU7cAFwzig.
