secret doorbel

[jacobsg]

Hi
Is it possible to add two or more different secret codes to arm the secret doorbel in the book microcontroller systems engineering? if possible could you guide me to what I need to do.

Thanks

Hello Gerhard

If you look at the program you will find a string comparison that is done using a string manipulation icon. The result from this is then used to drive a decision icon which decides whether or not to do a task. You should be able to add more keys by copying the comparison and decision code and simply comparing against different keys.

thanks. I am new to flowcode and battle with the technical names, could you be more specific as to where the string is
