PS. The top of the Chip has a circle on the top not a semi circle an actual circle on the top and its on the top left side. Is that the top were pin 8 is suppose to be?

    Cameron,

    Have you looked at the datasheet for the 555? A quick google search produced the·following link - http://www.national.com/mpf/LM/LM555.html

    Do a web search for "555 Timer" and you'll find all sorts of introductory information on this device. Spend some time reading.

    In terms of hooking it up to a Stamp, it depends on what you want to use it for and what you want the Stamp to do.

    You still need to read the datasheet since it has an explanation of how the device works and some sample circuits for different functions.

    cameron·if its to the left of the notch that just means pin 1 , I have a few schematics of 555 circuits for differant things, square wave, sound effects, what do you want to do with it or are you just looking for something in general?

    Here is a schematic for an IR Beacon that I made for a discussion in another thread. With this beacon you can use your stamp to detect it at 38kHz and if you make 3 of them then you can program your boe-bot to triangulate the position of your bot for mapping out the area and record it's routes.
