Thank You sir. Sir, I need the circuit diagram too.
I hv an AVR development board and what I understand is that I need to connect a RELAY ckt to the OUTPUT pins to the control the motors.
But I hv no idea abt how shall I connect the phone or SIM900 module to the AVR Atmega 8 development board and make it interpret the sms commands like ‘1’ for ON and ‘0’ for OFF.
I hv written a tentative program to control OUTPUT pins according to HIGH or LOW signal received at INPUT PINS but I hv no idea abt how to make the phone or SIM900 interpret that.
Plz Sir I need the complete CIRCUIT diagram & the components required too. Plz Sir help me.
Thnx n Regards,
Soubhik.
