Nathad Posted March 2, 2007 Report Share Posted March 2, 2007 I am trying to build a wireless switch using a 2.4Ghz transceiver.The receiver will turn on a LED when the transmitter sends an on signal, and off when it sends an off signal.It is critical that the transmitter has a long battery life, and that is why I want to send an on signal and then an off signal, rather than a continual on signal.I have two questions1. How do I wire the switch to the transceiver so that only a short pulse is sent when the switch is flipped?2.How do I maintain a lit LED when the on pulse is sent and then turn it off when the off pulse is sent.I have an electrical engineering back ground and should be able to figure this out, but after a few days of brainstorming I thought I'd ask some advice.Thank you for any light you can shedThe specific transceiver I'm trying to use can be found athttp://www.sparkfun.com/commerce/product_info.php?products_id=151 Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted March 2, 2007 Report Share Posted March 2, 2007 You can do this low tech if you like. With a single Transistor. Use a smaller capacitor for shorter time.and the steady part can be done with an SCR Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted March 2, 2007 Report Share Posted March 2, 2007 Here is with a relay and no transistor. Quote Link to comment Share on other sites More sharing options...
