The Serial.print() function prints the value on a single line but the Serial.println() function prints the value and moves the cursor to the following line.įor example, let’s define a char array and print it on the serial monitor window using a loop in Arduino. Inside the loop, we will get each array element using its index and print it using the Serial.print() or Serial.println() function. This command takes the same forms as Serial.print (). Here is the full code listing for this example. We’ll create a counter variable and print its value and keep incrementing it and send the data over UART every 250ms. Then you use the sprintf () function to combine our text and variables into a string. First, you’ll create in a character array to save the output string. In this example, we’ll send a string text message alongside a numeric variable on the same line. Here are the three lines of code you’ll need: char buffer40 sprintf(buffer, 'The d burritos are s degrees F', numBurritos, tempStr) Serial.println(buffer) Let’s break each line down. We can do that using a loop in Arduino.įor example, we can use a for loop that starts from the index 0 and ends at the array’s length, which we can get using the length() function. Prints data to the serial port as human-readable ASCII text followed by a carriage return character (ASCII 13, or '\r') and a newline character (ASCII 10, or ' '). Arduino Serial Print String
