/*Reading a serial ASCII-encoded string.This sketch demonstrates the Serial parseInt() function.It looks for an ASCII string of comma-separated values.It parses them into ints, and uses those to fade an RGB LED.Circuit: Common-Cathode RGB LED wired like so:- red anode: digital pin 3 th...

void serialEvent(Serial myPort) { // get the ASCII string: String inString = myPort.readStringUntil('\n'); if (inString != null) { // trim off any whitespace: inString = trim(inString); // split the string on the commas and convert the // resulting substrings into an integer a...
Serial.begin(9600); } voidloop(){ if(Serial.available()>0){ String data = Serial.readStringUntil('\n'); Serial.print("You sent me: "); Serial.println(data); } } Here we check if the Arduino has received data with Serial.available(). This will give you the number of bytes alread...
Because the while(!Serial); command will pause execution of the sketch until you open the serial port, this approach should not be used in environments where your Arduino-based solution is expected to run independently; for example when running on batteries without a USB connection. Table 4-2...

The PrintPlus class has functions to copy from a Stream class object. Examples of types inherited from Stream are HardwareSerial, SoftwareSerial, File, EthernetClient, WiFiClient, ... Example: There is a pair of functions copyFrom and copyFromUntil which wait for the next byte until timeout...
