This program starts from the number 3 and prints all I set the serial communication at 115200 baud on a nano, which should work, although the only thing that comes to mind is that it has a different driver chip than most arduinos (CH340). My goal is for it to be as fast as possible, so I'm trying to make it simple to achieve maximum speed. I've written a sketch that is supposed to generate prime numbers using the modulo operator, but I'm having trouble with it printing anything to the serial monitor. ![]()
