![]() 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. This function (given at the bottom) can be pasted in the beginning of the files where the function is needed. 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. ![]() 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. 39 ardprintf is a function that I hacked together which simulates printf over the serial connection. Inside the loop, we will get each array element using its index and print it using the Serial.print() or Serial.println() function. 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. 21 1 1 3 Add a comment 3 Answers Sorted by: 3 Do something like this: Start with your string and integer: String string 'PI is equal to ' int integer 3.1416 Then put this in your loop: Serial.print (string) //string here Serial.print (integer) //int here Serial.println () //change line Serial.print () doesn't change line. ![]() The character array elements are placed on certain indexes, and to print them, we need to get each of them individually. In Arduino, if we initialize an array using the int keyword, we must use a loop to print its elements.
