I am new to Arduino programing a need to complete a project sooner than I am able to lean how to write code effectively. The code should be simple enough for someone with a little experience with the SM5100B Cellular Shield.
The SM5100B Shield attaches to an Arduino Mega and needs to operate in the following way;
- only needs to send and receive SMS messages not calls.
- when the shield receives an SMS from an authorized phone number, it activates a digital output pin on for an adjustable amount of time, before switching said pin off. Normal position is off.
- two pins on the Mega board need to be digital input pins. When pin #1 receives an input it sends a customizable SMS to a set phone number, then when the input ceases to pin #1 another customizable SMS is sent to the same phone number. The program needs to be the same for pin #2, except with different SMS messages.
Basically the system needs to alert the end used via SMS, of when either input pin is on or off.
