I looked around, but I could not find a clear tutorial on how to do this, or even if it is possible. I would like to use serial communication to upload a sketch to one Arduino Uno/Mini from another Arduino Mega. I found tutorials on how to upload bootloaders like this, but I want to upload a sketch like this. If anyone could help, I would appreciate it (or tell me that it is impossible...)!
This should work also with a Mega as Programmer: Using an Arduino as an AVR ISP (In-System Programmer)
Yes, I found that tutorial before, but I want to know how to modify it to program an arbitrary sketch, not a bootloader.
Here's a good way - program a sketch stored on SD card.
