In the sketch given above, a new string is created and then printed for display in the Serial Monitor window. Shortening the String The string is shortened by replacing the 14th character in the string with a null terminating zero (2). This is element number 13 in the string array counting...
You can use the following statement to discard all data in the receive buffer: while(Serial.read() >= 0) ; // flush the receive buffer. Serial.write and Serial.print do not block. Older versions of Arduino would wait until all characters were sent before returning. Instead, characters ...
openFile("r"); Serial.println(f.size()); } } next Returns true while there are files in the directory to iterate over. It must be called before calling fileName(), fileSize(), and openFile() functions. fileName Returns the name of the current file pointed to by the internal ...
if(!getLocalTime(&timeinfo)){Serial.println("Failed to obtain time");return;} Then, print all details about the time in the Serial Monitor. Serial.println(&timeinfo,"%A, %B %d %Y %H:%M:%S");Serial.print("Day of week: ");Serial.println(&timeinfo,"%A");Serial.print("Month: "...
begin(115200); while (!Serial); // Leonardo/Micro #if defined(EPOXY_DUINO) Serial.setLineModeUnix(); #endif }Why isn't setLineModeUnix() simply made to be the default on EpoxyDuino? Because people write AUnit unit tests which they expect will pass on both the microcontroller and on ...
Serial.begin(57600); // delay(1000); } void loop() { } Open your Serial Monitor in the Arduino IDE and wait until the Arduino configures the BT module. Now your Bluetooth module is set to 57600 baud rate. You can try out a lot BCI (Brain Computer Interface) apps, because this hack...
Chapter 1described how to connect the Arduino serial port to your computer to upload sketches. The upload process sends data from your computer to Arduino and Arduino sends status messages back to the computer to confirm the transfer is working. The recipes here show how you can use this commu...

UnbufferedPrint out(Serial); out.printf("count of %s is %d\r\n", name, count); out.copyFrom(client); Providing string where Stream is required The StringReaderStream class can wrap a string or String into a Stream implementation. The string can be in PROGMEM. This allows to provide a ...
