Serial.print("The converted string into integer is: "); Serial.print(num); } void loop(){ } The code above declares two variables: "a" as a string data type and "num" as an integer data type. The string is converted to an integer using the "toInt()" function and the result is...
as the content of a JsonVariant // WARNING: the content of the String will be duplicated in the JsonDocument. String key = "sensor"; doc[key] = sensor; // It works with serialized() too: doc["sensor"] = serialized(sensor); // You also concatenate strings // WARNING: the content...
So, before we add the comma, we need to convert the value of the byte to a string using thestrfunction. Only then we can concatenate it with the comma. str(ord(byte)) + ',' The full print loop can be seen below. Note that the extra comma at the end of the print function is ...
But Arduino lacks this feature. So theworkaroundis not to compile all sources separately, but to concatenate them to one huge source file by including them in your source. This is done by e.g.#include "IRremote.hpp". But why not#include "IRremote.cpp"?

Don't use the + operator to concatenate Strings as it creates a full String of the all the parts before copying it to the result String. So instead of rtn = "123"+sb+"345"; // DO NOT do this use these statements that don't create any temporary Strings and, when rtn has been re...
See the attached file. I was not able to load a .xls file so I have included a .pdf to show you how the spreadsheet is created using a series of "=BIN2HEX(CONCATENATE($B7,$C7,$D7,$E7),1)" formulas to create the HEX codes you need. ...
