    Hi,
    well i think it depends on how many channels u want as output ,

    u should go for DTMF which can control 16 latches.

    I hope this solves ur problem

    Thanks and regards

    Default well

    A DTMF version will be good but i recommend a RC5 one if you can build one ....

    Do check out atmel website ... it has RC5 decoding libraries in code section .

    Also tsop 1738 work well with Ir encoded at 38 Khz and if its not around this freq does not give a good response . In my experiene The TSOP can be directly integrated to a uC do not forget to use a .1uF decouplic capacitor though .

    Default hmmm

    hi ,
    problem is tht wen two ppl are compiting n if both use rc5 decoding (which
    is most common ) it will be impossible to control ur own robo
    plz suggest me a way to build my own hex code
    wat i m thinking is
    to generate an hex code using 8051 n send it serially to ir diode at 38 khz

    thnks very much
    regards

    Default well

    there is problem you see when there are two transmitter both at 38 Khz there will be a collision and it wont matter what encoding you are using . Also 8051 RC5 transmitting code and reciving code is availible on the net on many site do check it out .
