Question

Arduino does not allow you to do a printf() statement to the terminal which can make things difficult to output. To make this easier, create a program that uses sprintf() to print data to a string. That string should then be printed out using a single Arduino’s Serial.Print() command.

As an example, if you have three wall sensors with three ints to print out, you want your output to look like this:

Wall Sensor 1 = 12 cm.Wall Sensor 2 = 15 cm.Wall Sensor 3 = 10 cm.

Where 12, 15, and 10 are all ints that are converted into the above long string using sprintf().

Explanation / Answer

int wallSensor1 = 12;

int wallSensor2 = 15;

int wallSensor3 = 10;

void setup() {

Serial.begin(9600);

}

void loop() {

char buffer[100];// take buffer size as long as the string size.

sprintf(buffer, "Wall Sensor 1= %d cm. Wall Sensor 2= %d cm. Wall Sensor 3= %d cm. ", wallSensor1,wallSensor2,wallSensor3);

Serial.println(buffer);

}

// Like is Expacted. Thank you
