Programming The Lock Bits Using Arduino ISP with AVRDUDE

Intoduction: Protecting The Arduino Uploaded Program Codes If you want to sell the final product developed with Arduino, then you need to protect the firmware from cloning. Similarly, you need the protection as well when selling an embedded software by selling the programmed microcontroller chip. Fortunately, there is a lock bits fuse that that is programmable using the ICSP interface. […]
