    i wish to control a servo using a cellphone.
    How it should work.
    1. A call from a know phone number calls a sim900 circuit.
    2. Microcontoller check if the call is from a know phone number, if yes call is answered and a password is expected, DTMF decoder is used to check the password
    3. If the password is correct the servo motor turns 180 degrees n back to 0
    degrees, finish!

    i have made a working model using arduion UNO & icomsat gsm shield,

    now i want to build the same circuit by manually connecting all the components instead of arduino n shield on a breadboard

    How should i go about doing it? what all components will i need?

    thanks in advance!

    You will need a microcontroller and a GSM module.

    Check out the schematics of the GSM shield and how it connects to the Arduino for some idea.
