Describe the problem The first output printed to Serial Monitor after an upload is some "garbage" characters. To reproduce Equipment Arduino board that uses the ATmega16U2 USB chip: Arduino Uno Arduino Uno Mini
To read data from the serial monitor, first, you need to check whether user entered data or not. To check user data availability, you need to useSerial.available()function/command. When the user enters the data on the serial monitor, Arduino setsSerial.available()to return ‘1’ and in ...

The Arduino IDE (described in Recipe 1.3) provides a Serial Monitor (shown in Figure 4-1) to display serial data sent from Arduino. Figure 4-1. Arduino Serial Monitor screen You can also send data from the Serial Monitor to Arduino by entering text in the text box to the left of the...
/* Beginning Sensor Networks, 2nd Edition This sketch demonstrates a basic sensor node using a DHT22 sensor to read temperature and humidity printing the results in the serial monitor. Dr. Charles Bell */ #include <DHT.h> #include <DHT_U.h> #define DHTPIN 2 // Digital pin connected to...
The value of RPM can also be used to calculate the distance travelled by a rotating wheel or disc. Instead of printing values to Serial monitor this device can be made more useful by connecting a LCD display (16*2) and battery for better usage....
Describe the problem A Bluescreen of Death occurs after about 30 seconds when the board is running a sketch program that causes continuous printing to Serial Monitor: To reproduce Upload a sketch that causes the board to print continuous...
After the upload finished, open the serial monitor. You should get an output similar to figure 1, which shows the HMAC code for our message. Figure 1 –HMAC calculated on the ESP32. To confirm our result is correct, we can use this online tool, which allows to compute the HMAC of a...
Creating and Printing the String In the sketch given above, a new string is created and then printed for display in the Serial Monitor window. Shortening the String The string is shortened by replacing the 14th character in the string with a null terminating zero (2). This is element number...
