The real power of the Arduino comes when you combine an Arduino, a sketch, and one or more peripherals. These peripherals are devices that can sense the world (sensors) or change something in it (actuators). In this series of tutorials, you will learn how to use some of the most comm...

In certain scenarios, you may encounter the need to concatenate strings in Arduino while also incorporating C-style strings (char arrays). This advanced approach involves using the c_str() function to convert String objects to C-style strings, allowing for seamless integration with the append oper...
THe 72x8 driver chips define "DIGIT1" as the right-most digit in the display, and "DIGIT8" as the left-most digit. When using c-string char arrays with this library, array element[0]corresponds to DIGIT8 and array element[7]corresponds to DIGIT1. When using Single Digit Update mode,...
You could combine them like this: Serial.print("At "); Serial.print(t); Serial.print(" seconds, speed = "); Serial.print(s); Serial.print(", distance = ");Serial.println(d); Or you could use the insertion-style capability of the compiler used by Arduino to format your print ...

It determines to what type we must cast parsed value arrays (char* for "s", int32_t for "L"). We could set each solumn to be strings like "sssssss", however this would use more memory than it's really needed. If we wanted to store a large array of small numerical values (e....
