Good day , I’m working with project right now that will display text and logo in RGB LED strip using GSM module and arduino . I’m al ready done with that but the problem is My whole project requires a Admin
this is the scenario
student texted the number of GSM module then it will temporary stored (maybe on array)
then the admin need to approve it ( Display or Delete that message )
To display or delete message Admin requires a password and command like this:
STI123 Display MGS1
(password) (command) (message that stored)
can you give me example codes or some PDF to understand more about GSM module TIA guys.
