Topic: reading typed numbers during calls (Read 562 times) previous topic - next topic


Hello, :)

I am building an alarm system with an SIM900 shield and arduino UNO. I programmed it to call me when a movement is detected and it works. So now, I would like it to read numbers that I type after have picked the call up.

Do you know when you call customer services and they tell you "type 1 in this case", "type 2 to go to menu" ecc... I would like to type 1 to turn the alarm off if I am at home and I know it turned on by mistake.

I looked up some library references and stuff but I did not find any useful command...and AT commands are Chinese to me...

How can I (Arduino) read numbers the caller types while calling?

Thank you very much!
