File dataFile = SD.open ("datalog.txt"); It will return false if it fails to open the file, so check dataFile before using it.

Splet13. dec. 2014 · Your first problem is that there is no way for schar to contain two characters in the first place; Since schar is declared as a char, it can only contain one character. You need to make a String out of the serial input. Serial.read () only returns one character at a time, so you will need to make sure you iterate over all the input. SpletIn particular, a switch statement compares the value of a variable to the values specified in the case statements. When a case statement is found whose value matches that of the variable, the code in that case statement is run. The break keyword makes the switch statement exit, and is typically used at the end of each case.
