    There is not enough information·provided in your message·for anyone·to help you. Is the TSOP part of a circuit you built?

    From what I understand, you want to be able to have the stamp make certain I/O pins high, turning on the desired led color via RF trasmitter?

    Well I must Control 3 colors (red, yellow and green) of led's

    so there are 3 circuits One red, one yellow and one green. Each circuit has a triac (=TIC226·) which the Basic Stamp must swich on. now is my problem how I should write the program.

    The Inputs are given by a remote control. And a IR receiver·provides the signal to the·Basic stamp.

    Lets Say that nr 1: Green

    ···················nr 2: Red

    ·················· Nr 3: Yellow



    If my first task is nr 1 and the three green led's are lighting up, must these led's·switch off·automatically If my next task ( Nr2 or Nr3) is given.



    thanks a lot

    Chapter 2, Activity #3 in IR Remote with the Boe-Bot has an example program that can be adjusted to control your LEDs. Let's say your Green LED is connected to P5, the red to P7 and the yellow to P9. The SELECT...CASE command could look something like this:

    LOW 5
    LOW 7
    LOW 9

    SELECT remoteCode

    · CASE 1
    ··· HIGH 5
    · CASE 2
    ··· HIGH 7
    · CASE 3
    ··· HIGH 9

    ENDSELECT

    Note: IR Remote with the Boe-Bot is available for download from www.parallax.com -> Downloads -> Stamps in Class Tutorials.

    BTW, I didn't look up your triac. If it's active-low, you will need to swap all the HIGH commands for LOW and visa-versa. Try prototyping it with low current LED circuits (normal LEDs with 470 ohm resistors in series) first before adding clusters of LEDs and drivers into the mix.

    Thanks a lot, The led circuit is working, 3 led's in serie with a TIC226M. @ School i will test my circuit with the basic stamp
    I have got one more question, does the basic stamp provides the clock radio for the IR sensor? ore do you have to work with an extra Timer ic?

    The IR·receiver is a 3-pin device with all the necessary electronics built-in. Download that IR Remote·with the Boe-Bot text and check out Activity #1 (Pages 1 to 8).· The PDF is available for download from www.parallax.com -> Downloads -> Stamps in Class Tutorials.· You can also download it from the IR Remote with the Boe-Bot product page.
