||||
I started making a machine for pulling a ribbon from PET bottles into a rod for a 3D printer. I found a ready-made PetPull2 machine and it seemed wonderful to me. However, there was one downside. For some reason, the author of the machine uploads for him only the compiled firmware in hex format.
|
||||
I decided that maybe it would be a good practice for me to try to write my own firmware. And so that there are no more questions - I took instead of arduino nano - esp8266. The author of the machine does not have firmware for this controller, and the microcontroller itself is currently in short supply of semiconductors - cheaper than Arduino nano.
