Serial.write ( '\n' ) /*A new line character will be written */ Serial.write ( 36 ) /*byte will be written having value 36 = > '$'character */ Serial write can be declared in three different formats as shown below: Serial write is simpler and faster as compared to serial print because serial write returns data in binary while serial print converts data from ASCII to binary. To send digits of numbers represented by characters user Serial.print() instead of Serial.write() function. Serial.write() function returns the total number of bytes written. Data can either be sent as s byte or series of bytes. Serial.write() Arduino functions send data serially in the form of binary. Here we type the word “ Hello” which is shown in output terminal as follows: The data will be read by serial read and shown on serial monitor. Type any word on the serial monitor and press Ctrl Enter. In the loop section if condition is used to check whether any data is available at serial port or not if the data is available, it will store the read data into variable ByteReceived and using Serial.print() the received data is printed on serial monitor. Serial.print ( " Received Serial Data is: " ) Ībove code initialized a new variable at start with name “ ByteReceived” next in void setup part serial communication is begin using baud rate. prints the received data on serial monitor check for the serial data at serial port Serial.begin ( 9600 ) // Serial communication begin to read data Int ByteReceived = 0 // INT for received serial data
