Hello everyone ..
i have a problem, i'm a new graduated electrical engineer, and i want to make a project for the office that i work for.
basicly its a low budget project . i want to put a wirless device (transmitter) in each office to be used as calling bill to call the kitchen boy (i dont know what to call him !!), i have about 5 to 6 offices, and i want to put one reciever in the kitchen with a led for each office ,so that when anyone in any office calles the kitchen boy , the corresponding led will blink.
the problem is :
all the transmitters will use the same RF channel (because i intend to use one channel reciever to meet my low budget conditions), so how can i give each transmitter a unique identefier ?!!!
any ideas guys !!
help me please ..
