Arduino board programmer

I make this project arduino_sketches/Atmega_Board_Programmer.ino at master · nickgammon/arduino_sketches · GitHub When i open serial monitor i have unknow symbol what this problem ? How to use this program from serial monitor, what exist command from serial monitor ?

That sketch sets the baudrate to 115200. You should set the serial monitor to the same. The default is 9600.

Ok now i see normal symbol, but what send symbol to run this program on arduino ?

have reply this topic ?

minde1:
but what send symbol to run this program on arduino ?

Nothing, just connect it up and if an arduino is connected to it then the boot loader will be programmed onto it.
