Serial interface for ATTiny that allows you to print different data types to an arduino's serial monitor. Doesn't require any extra serial cables/devices. This uses SoftwareSerial so it's not all too ...

Debugging embedded software on Arduino can be challenging, especially if you rely on Serial.print() statements to monitor the program flow and variables. Serial.print() can be slow, intrusive, and ...

The Serial Plotter built into the Arduino IDE creates graphs from numerical data. Unfortunately, there is no user manual for it. One of the strong points of Arduino is its easy-to-use serial port ...

In this Arduino bluetooth tutorial we will connect two HC-05 bluetooth modules together using Arduino, and make them communicate using master slave configuration.

But using a debugger might need additional hardware (most times expensive) and also additional time. Being an Arduino fan boy, one thing we all can agree is using serial print statements for debugging ...
