Guest Yevgenip Posted February 6, 2005 Report Share Posted February 6, 2005 Hi! I'm up for a big project this time: a model boat.The first thing I need is to understand how the remote control works. Ever seen those HUGE remote controlles for model airplanes with those big anntenas? this is what I'm thinking about. My question is how can I transmit information like speed (i.e. potentiometer resistance) and on/off (i.e 0/1).Thanks. Quote Link to comment Share on other sites More sharing options...
Guest Alun Posted February 6, 2005 Report Share Posted February 6, 2005 I've been thinking about designing a remote control too, check out the following links:http://www.rentron.com/RF-Remote.htmhttp://www.rentron.com/ruf-bot.htmhttp://jap.hu/electronic/codec.htmlhttp://web.telia.com/~u85920178/tx/cw-am_00.htmhttp://web.telia.com/~u85920178/rx/zn414.htmhttp://web.telia.com/~u85920178/use/rc-prop.htm Quote Link to comment Share on other sites More sharing options...

Guest Yevgenip Posted February 9, 2005 Report Share Posted February 9, 2005 I just didn't understand how I can vary a motor's speed in remote control. Quote Link to comment Share on other sites More sharing options...

Guest Yevgenip Posted February 11, 2005 Report Share Posted February 11, 2005 PWM is o.k. So I have to have PICs and stuff? don't have much experience in that area. any alternatives?Thanks. Quote Link to comment Share on other sites More sharing options...

Guest Alun Posted February 13, 2005 Report Share Posted February 13, 2005 Thanks for the links Ante!I haven't got as far as speed control, one Idea I've had is to use a DTMF dialler and decoder chip connected to a transmitter and receiver respectively. I could then transmit 4-bit binary numbers and get it to turn motors on and off forward/reverse etc. Quote Link to comment Share on other sites More sharing options...
