Stopping Input buffering from skipping over Serial.read() commands WITHOUT setting the Serial Monitor to "No new Lines"

[johnwasser]

You seem to want to input a number. In that case you should probably use:
int minimum = Serial.parseInt();
or
float minimum = Serial.parseFloat();

The .parseInt()/.parseFloat() methods will throw away characters that aren't part of a number ("+-.0123456789") and then read a number until it finds something that doesn't look like a number or a full second goes by without any input.

Yes, if you have a Serial.parseInt() right after the previous Serial.parseInt() then it will generally read a zero value because the second number was not sent within the one-second timeout. One way to mitigate that problem:

  int intVar = Serial.parseInt();

  // Allow time for any line ending characters to arrive.
  delay(500); 

  // Clear the input buffer
  while (Serial.read() != -1) {}

  // Prompt for the next input
  Serial.println(F("Input a number here (decimals are welcome!): "));

  // Wait for the first character to arrive
  while (Serial.available() == 0) {}

  // Read the value
  float floatVar = Serial.parsefloat();

Sorry-- Didn't see this reply until now. I just got around to testing it and it worked a more impressive miracle than when Moses split the water in the bible. But before I do anything with it, Ima go on a spiritual adventure to figure out the specifics of pointers because they have now caught my limited attention span thanks to your code. Thanks again-- you're the best

Do you think the same problem will occur if I try to use parseInt(), then parsefloat()?

[johnwasser]

Yes. Definitely.

The pointer used to parse the double value is not really necessary, it’s meant to ensure you actually entered something that could be parsed as a number (at least the start of the string)

The wokwi simulator can do all the line endings settings.

For a few wokwi features, one must brave to edit the *.json file, that which informs the additional parts and wiring.

I could nutshell it, but I'm prone to, well never mind:
