Yes sir.
It has RF433X which gets data from HT12E encoder which gets its data from PIC microcontroller.But how is PIC microcontroller able to send the data to HT12E about which lane is the ambulance travelling?
Acoording to the link i have put in the post,It said the driver has remote where the lane number is selected.But how is that remote connected to PIC microcontroller ,This we are unable to understand.
