In this tutorial, I will be going through the steps on how to set up the Arduino serial monitor so you can debug and interact with a program.
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 ...
Either click on the button just below the serial monitor icon and choose New Tab, or use Ctrl+Shift+N keys.Give file's name bitmap.h and click OK button Copy the below code and paste it to the created bitmap.h file. This code contains the bitmap array for DIYables logo. #...

That should get you started printing text and the decimal value of integers. See Recipe 4.2 for more detail on print formatting options. You may want to consider a third-party terminal program that has more features than Serial Monitor. Displaying data in text or binary format (or both), di...
The STM32L432 is programmed using the Arduino IDE via the USB connector and serial data can be displayed on the serial monitor to verify performance and proper function, etc. But it is intended to be powered by a small 150 mAH LiPo battery for wireless sensing applications. The STM32L4 is...
Printing the StringThe string can be printed to the Serial Monitor window just like a character array string.Convert the String to Upper-caseThe string object my_str that was created, has a number of functions or methods that can be operated on it. These methods are invoked by using the ...
