Hello, I had a simple question about the set baud rate method in the SoftwareSerial Library. Does the baudrate only have 2 symbols, or more than that? How do i test this if I want to find out for myself?
Does the baudrate only have 2 symbols
That question does not make sense. A baud rate is the number of bits per second that are send/received. How does that relate to "2 symbols"?

In that article, it talks about how baud rate is a little different than bit/sec. That's what i meant.

No, baud rate is bits per second. That is different from bytes/second, because the are start and stop bis involved. The number of start and stop bits is configurable for the HardwareSerial class. SoftwareSerial assumes 1 of each.
Hello, I don't think you quite read the article, but baud rates if it really is bit/sec, then it will have 2 symbols. one symbol for a 1 and another for a 0. However, baud rates can be configured to have more than 2 symbols. Does that clarify?
Multilevel modulation which provides more than 2 states per symbol needs a suitable modulator to create the
extra states, and Arduinos have no such capability, so for all practical reasons baud rates and bits per sec are the same.
