Hi All,
I would like to ask about this project
I like a build a transmitter and receiver. Hopefully the transmitter is trasnmitting a constant code , The receiver picks up this code ..do nothing
Once these two pairs are out by maybe 2 to 5metres , the receiver will make a Buzzer to sound and maybe LED to lightup,,
Scenario : Mommy put receiver at wrist .Son wear the transmitter on wrist too. GO shopping ,son playfully run away to see toys and lost her mommy .
Once 'out of range' between the 2 , mommy wrist buzzer n LED will light up.
Is it simple to do these 2 parts? I just need the TXM to produce some ''codes'' to identify its receiver which maybe check for same ''codes'' to tell that these 2 are a pair . Once out of zone, one of them buzz
what components must I need? Anybody tried this stuff before and likes to share experiece or circuit designs?
What is transceivers?? can they do the job better than txm or recv?
I hope there is no PIC control here as I am not very knowledgable with PIC
Anybodylikes to help me out ?
WIth regards,
B
