I have been trying this for hours and still dont work

Code is:

' {$STAMP BS2}
' {$PBASIC 2.5}
irdetectright VAR Bit
DO
·· FREQOUT 2, 1, 38500
·· irdetectright = IN0
·· DEBUG HOME, "irdetectright = ", BIN1 irdetectright
·· PAUSE 100
LOOP
why is irdetectright = 0 all the time

    There doesn't seem to be any problem with the code -- you probably have something misconnected; that's very easy to do.

    You might try a different input pin if you're absolutely sure your circuit is correct (trust me, we all fall prey to our egos on this one...).

    What do you mean, "touch the receiver"? -- do you have loose connection? This happens in breadboards all the time. You probably don't want to hear this, but when I get to this point of frustration I pull the components and start from scratch. There's only a few components involved, so it won't take long.

    Remember while you are doing it that plugging the LED in backward will result in no light. You have to make sure that the anode and cathode are connected as indicated in the schematic and wiring diagram. For a review of LED connections (this applies to the IR LED too), see pages 45 to 51 in Robotics with the Boe-Bot v2.2.

    Try this:

    ' {$STAMP BS2}
    ' {$PBASIC 2.5}

    DEBUG "Program running..."

    HIGH 15

    Also, try following the step by step instructions on pages 45 to 52 in Robotics with the Boe-Bot v2.2. If that's not what your working from, it's available for download from www.parallax.com -> Downloads -> Stamps in Class Tutorials.

    When you download the program (from the previous post), does the Debug Terminal appear with the message "Program Running..."?

    Make sure your BASIC Stamp is properly inserted into the socket. Unplug power from your board, then press down firmly with your thumb on the BASIC Stamp. Reconnect power and try again.

    Make sure to follow the step-by-step instructions in Robotics with the Boe-Bot, in Chapter 7, Activity #1.

    idk but when i touch the receiver it turns. but it looks like the irled arnt working how can i fix that?

    Fluorescent lights can cause the IR recievers say they are detecting IR when they really aren't. However, they will not make the irDetectRight variable be 0 all the time. Only occasionally.

    The instructions in Chapter 7, Activity #1 in Robotics with the Boe-Bot v.2.2 show how you should be pointing the IR LEDs and receivers.

    The IR LEDs and receivers are not designed to be contact sensors. They should not respond to touch. They should respond to an obstacle in front of them. See page 236.

    Um, well, I'm glad to hear it works now. If they are the receivers that come with the Boe-Bot, they are supposed to have the metal case and the metal X over the black hemisphere. Removing the metal X won't hurt it, but it's always worked without removing it.

    Yes, go to www.parallax.com -> Downloads -> Stamps in Class Tutorials

    Download What's a Microcontroller v2.2.

    Chapter 3 has lots of pushbutton examples.
