  1. I have constructed a transmitter and a receiver using simple modules. The transmitter has four inputs which are displayed on output pins at the receiver. I need a chip that can display differing high pulses depending on which output pin is activated. For example output pin1 high gives two short pulses (ths could be used to give two short LED flashes), output pin2 gives two longer pulses, ouput pin3 gives one long constant pulse and so on. I'm quite a newbie at this and was wondering if it is possible to buy ready made chips to do this chip or would it involve some programming? If it would involve programming how easy or difficult would this be? Any help would be greatly appreciated. Thanks, James
  2. Hello, I was wondering if anyone would be able to offer any help or advice on a project i'm currently undertaking. I'm wishing to make one reciever that is able to distinguish between 5 different transmitters. For example if a signal from transmitter 1 is received, LED no.1, if from transmitter 2, LED no.2 and so on. I have very basic electronics knowledge and have done some research into this area and have found an encoder/decoder chipset that might be able to help do this for me - RF600E & RF600D. The decoder can learn up to 7 different encoders and has a range of up to 20 metres. I've also found the RF600T which can do a similar thing but also has low battery warnings and it confirms signal transmission. Apparently these are easy to use chipsets which can be inserted into any RF circuit. This is my problem as I have limited electronics knowledge i was wondering if anyone could help point me in the right direction of a suitable RF circuit or what i would need if I were to design my own. Any help would be greatly appreciated James
