Convert char to String in Arduino

In Arduino, you can convert a char to a String using the String() constructor. Here is an example:

char ch = 'A';     // Declare a char variable
String str = String(ch);   // Convert the char to a String

In this example, we declare a char variable ch with the value ‘A’. We then use the String() constructor to convert the char to a String and assign it to a String variable str.

You can also concatenate multiple char values into a String using the += operator. For example:

char ch1 = 'H';
char ch2 = 'i';
String str = "";
str += ch1;
str += ch2;

In this example, we declare two char variables ch1 and ch2 with the values ‘H’ and ‘i’, respectively. We then declare an empty String variable str and use the += operator to concatenate the char values into the String. The final value of str will be “Hi”.
