hy all, i'm new here, i dont know c or assembler, but if i have the code, i could write in my mcu and...the toy is done... So, i need a code or already compiled for sending AT commands to mobile phone when i put one pin at the ground. I sow many exaplmes here, but nothing alredy done for what i need... also, i need tu tell me what mcu and what phone i must use.. Thank you very much.
I think that you need is very simple, but will not find exactly how you need. You need modify a sample code to do this, and at this point a knowledge in c language is necessary.
Try the PIC16F84A and a Nokia 6610 mobile phone. These are the simplest devices you can ever find.
The Nokia 6610 has a serial cable that can be connected to the PC serial port.
You will cut the cable and connect the phone to the microcontroller directly.
yes, is a bit more complicated, but i saw many projects without max converter. now i have a sony ericcson 628 and a1018. a understant thats working without pic without max... am i right?
