Standalone AVR programmer This sketch can be used to let one Arduino program a sketch or bootloader into another one, using the ISP programming pins. This sketch is based on OptiLoader, but modified ...

Here we are using an Arduino UNO board to program the Atmega 328PU chip. UNO board is acting as an ISP (In System Programming) programmer to program the chip on a bread board or on a PCB. This method ...

We found this Arduino AVR ISP programmer particularly interesting. AVR microcontrollers can utilize an interface called In-System-Programming. ISP allows the chip to be programmed or reprogrammed ...
