please help, my knowledge of electronics is pretty limited; maybe someone could help me figure out how to put together the correct componets to do this experiment. here is my idea: a 12v radio transmitter that would send out a signal to a remote 12v receiver. the transmitter would be activated by a 12v automobile switch, and then output a signal; the time the signal is activated needs to be adjustable. the receiever would then activate a flashing light. transmitter componets: 12v switch 12v timer 12 v relay 12v voltage to frequency converter 12v transmitter reciever componets: 12v receiver 12v frequency to voltage converter 12v relay 12v flasher 12v light thank you, have a good day...........
