    Difference between IR receivers

    What is the difference between TSOP 1833 and 1738 other than the frequency range? Is there any way in which the change in IR frequency can be detected? Also is it always necessary to have a different supply for IR LED and IR reciever ? If so which one should be more?

    1 second Interrupt from 8051?

    If u need a 1 sec interrupt IanP's method is the best it takes less memory space . The other method suggested might work but why on earth would anyone want take a longer way out when there is a shorter one? unless you are doing many other things on the 89C51 and the registers are not free. Even...

    Help me make an IR remote controller with a PIC16C745/765

    hello hello A TSOP 1738 is a very cool reciever so that chip is alright. For input a normal port would do that way you can use RX/TX for other purposes, also if you want to use the same board with more sensors in the future using a port would make sense. I don't know about encoding a binary no...

    # The Microcontroller Tutorial #

    I agree stepper motors suck as well. On the other hand stepper motors are explained well in any site that talks about micromouse programming. E.g www.micrmouseinfo.com
