When you declare the array, you’re declaring that it will store pointers to char variables. Though this may seem a little strange at first, it isn’t hard to get used to, and generally, in Arduino, you’re not dealing very extensively in strings. Interview: David Cuartielles David Cu...
Arrays are made up of contiguous memory elements (of type char - a byte) and are allocated by the compiler. You can have an array of any type so: char char_array[10];// Allocates 10 char of 1bytes each = 10 bytes. int int_array[10]; // Allocates 10 integers of 2 bytes each...

char *payload = "Hello HMAC SHA 256!"; We will also need to declare a byte array to store the authentication code generated by applying the HMAC. As mentioned in the introductory section, the output will have 32 bytes, which should be the size of the array. ...
