GSM BASED MOBILE CAR LAND ROVER In this project we show that how we control the movement of any small robot with the help of mobile phone. By using this logic we not only control the movement of vehicle but also switch on/off other accessories on robot. With the help of mobile phone we switch on/off the camera on the robot,we switch on/off the fountain also, with the help of fountain we spray the water vapour on the fire. Our project is to be divided into few parts. Vehicle control. Fountain sprayer. View scanner by camera. CONCEPT: In this project we use smart logic and control system of embedded system by using microcontroller. In this project we use ic 89c51 as a main processor.. microcontroller sense the signal and drive the motor of the robotic vehicle. . Ist circuit is ic 8870. IC 8870 is a bcd to dtmf decoder. So our first part of the circuit is our dtmf decoder. This part is very much necessary, without using this part is not possible to interact with the mobile phone or dtmf based any phone. Whenever we press any switch from the transmitter phone then transmitter transmit some signal as per the switch press. So on every press switch there is a different signal Frequency 1209 1336 1477 1633 697 1 2 3 A 770 4 5 6 B 852 7 8 9 C 941 * 0 # D
