    Default IR help...

    hi,

    i needed some information about IR detection and if posible any ciruit using PIC16f84.

    I want to develope IR detection module for my PIC based robot for obstacle detection. Basically, it can move arround without bumping into anything..

    Is there any other option apart from IR..just wanted to know this

    can anybody help..


    thanks

    Default yep

    Try Sonar ( but its not recommend for beginners )

    Any way IR is simple ..... check the tutorials on the site ... to get the basic concept . And once you done youll be able to write your own code . Its very simple .

    rv,
    Go o visha and ask for an ir pair[comes for around 14 bucks]

    there are 2 ways u can,
    one way is a simple circuit to power the ir here
    http://www.geocities.com/gear996/sub...#sectionsensor

    The other way is to pulse the emouuter at a fixed rate say 40Khz
    Detectors for 38,37 and 40 Khz are readily available from "electronic" shops .they are the same kind found in ur TV.
    it's black in color with 3 leads and costs 30 bucks

    pls can anyone help me in interfacing tsop1736 to microcontroller port .its very urgent.
    can someone suggest me a scheme so that i can mount 4 sensors and 4 ir leds such that they can be used for line detection ( the respected receiver should receive only transmitted ir not directly) :?: :?
