How do I save an Arduino hex file?
Follow these steps:
- In the Arduino IDE select Sketch > Export Compiled Binary . This performs a compile. Once complete, this command places a copy of the compiled . hex file into the directory of your sketch.
- Then either browse to the sketch folder or in the IDE select Sketch > Show Sketch Folder .
Can I read program from Arduino?
The Arduino bootloader is a variant of the original STK500 protocol (1. x). The character ‘t’ (ASCII 0x74) is the “Read Page” command. So perhaps it is possible to pull the program out through the serial port via the bootloader using AVRDUDE… But at best I reckon it will take some fancy timing to pull it off.

How to lock atmega328p-au for sketch read?
Just program both LB1 and LB2 (IMPORTANT: the note on the datasheet says “Program the Fuse bits and Boot Lock bits before programming the LB1 and LB2.”).
How to protect my program in ATmega328?
But you will have to use avrdude from the command-line to change the lock bits. The IDE is not a good choice for doing that. It may not even be possible to do from the IDE. There is no way to simultaneously protect your code AND use the standard arduino bootloader and tools.
Is there a way to read the ATmega flash memory?
You can access the flash memory (and so read the binary) from the outside (with a ISP programmer) or the inside (with some code). As for the outside “attacks”, the atmega has some fuse bits (read this answer for more info). Particularly the Lock Bit Protection ones can prevent anyone from reading and writing the flash and eeprom.
