How I can convert String object to integer? Thanks.
I use the below when sending servo positions to the arduino as strings, which are captured as the string "readstring"
Serial.println(readstring); //so you can see the captured string
char carray[readstring.length() + 1]; //determine size of the array
readstring.toCharArray(carray, sizeof(carray)); //put readstringinto an array
int n = atoi(carray); //convert the array into an Integer
Thank you so much
