Use theatoi()Function to Convertchartointin Arduino Theatoi()function is a standard C library function that converts a string (character array) containing numerical representation into its integer equivalent. voidsetup(){Serial.begin(9600);charcharValue[]="1234";intintValue=atoi(charValue);Serial....
In Arduino, a string is a sequence of characters that can be manipulated using various functions. Char arrays, on the other hand, are a lower-level representation of strings. They are often used for more efficient memory management and compatibility with C-style strings. When you need to pass...
