Hello Guys
I have just recently realized a project that involves connecting a PIC16f877A to Siemens C25 phone to send and receive AT commands. This system can make a call or calls, send messages, read messages and interpret them either to switch on lamps or do what ever thing you wish to do. While browsing the internet, I realise that there are so many people out there trying to realize similar project. in exchange for a small financial compensation, I have decided to guide anyone who ones to realise similar project but does not have enough time to google the net. What is annoying about searching the net is that they never go directly to the point. I have spent a lot of money and time to realize this project. PIC16f977A is very very expensive here in Cameroon and having access to the internet is also very expensive since I am using a cybercafé. Having internet connection at home is something that is meant for the rich unfortunately I am not one of them. Hey there are scammers out there so to clear your fears, I will send you the tutorials step by step if you find it helpful that is when you will compensate me. I have divided this tutorial in three sections;
1 The circuit diagram
2 The AT commands
3 The source code.
I have also realize a dot matrix display that can display information stored in an eeprom or can be connected to the computer via the serial port to display info that has been typed in a small software that I wrote in Turbo C++. If you are interested then contact me at
