I am doing a automation project to unlock door via SMS.
I am using an Arduino UNO and SIM300 with a max232circuit in between.
The gsm module to hyperterminal interaction is working, ARDUINO - MAX232 to hyperterminal is working.
But when i combine them all, I don't get any result.
I am using SoftwareSerial mySerial(2, 3) in my program.

Can you send me your interfacing circuit diagram.
I use P89v51Rd2 means 5V microcontroller and my gsm module (SIM900) is working at 4.2V, so how can i connect my Micro RX, TX which is at 5V to SIM900 RX, TX which is 4.2V support.
Please help me to design my circuit.
Thanks in advance.

Input Voltage : 8.0V
Input Current : 700mA
P1 - 2-4
P3 - 1-3 AND 6-8
Insert SIM Card
Then power up the module using Power on button.
System LED (Red) : ON
Net LED (Green) : Blinks few seconds and then OFF
It means SIM card is registered to Network.
Then your Module is ready to transmissi

Hi...I am currently doing a final year project on home alarm systems. I am going to use the gsm (sim340E) to interface with the pic18f4550, but i dont have an idea of how to find the scehmatic diagram. Any suggestions? . Another thing is, I saw a post on this forum on a gsm interacfing with a PIC16f controller. Is it possible to use that (...)

Actually I need to decode DTMF tones from the speaker of the local telephone or gsm modem. My main requirement is that I want to detect the key pressing using this. I have tried with 8870 decoder. But i found circuits which comes directly from the telephone lines where as my ultimate application has gsm modem in lead. Like in simple lang

Obviously i need to do an interfacing. Which interfacing would be better??? I think usb interfacing is much harder than the serial one. My question is what program i need to burn in my pic in order to detect a particular sms and execute something upon that(like turning a pin high or low). Also if anyone could provide the circuit (...)
