I am trying a wireless microprocessor based road safety device.
My device consists of two parts. An FM (I am using a walkie talkie for this) transmitter and an FM reciever.The FM The transmitter
is attached to a signboard/traffic signal/direction board .The reciever is inside the vehicle.
Transmitter
This is a wireless transmitter which uses FM frequency(I am using a walkie talkie for this) to transmit wireless signals to the reciever inside the
vehicle as soon as the vehicle comes in range with the transmitter on sign board say 1 meter .It consists of ATMega 8515
Microprocessor which which I want to code to send a particular binary code (....or some other type of code ....Please help me in this part)(which depends on what the sign board
is Eg.If the sign board means slippery road ahead.and the code of this message is "1",it will transmit "1" in
the form of binary signal to the reciever device.
Reciever
The FM reciever (I am using a walkie talkie for this) will pickup the binary code and transfer it to the microprocessor(ATmega 8515) which will convert it
into digital signal and find the message that matches the code "1"(i.e. slippery road ahead)in the flash
storage device(memory " ATMEL608 24C512 . PI18 A ")where many messages are stored in the local language of the driver .finally the message
will be transfered to the speaker of the vehicle . thus the vehicle driver will come to know that the road is
slippery and he/she will slow down .
LIST OF COMPONENTS THAT I HAVE QUANTITY
ATMEGA 8515 16PU 0621 2
ATMEL608 24C512 . PI18 A 1
pROGRAMMER FOR ATMEGA 8515 + PROGRAMMING SOFTWARE
UNFORTUNATELY ,I do not know how to make the circuit for the above device . can someone help me with the circuit of the transmitter and reciever parts .
