i don't understand where to plug the wires ,cap, and resistor on those pins.i have the schematic from pg101.pg 40-41 in the Stamp Works book it tells specific socket locations for the circuit described .i was lookin for another example.

well I managed to to find a good example between a simple pin schematic and this video http://www.youtube.com/watch?v=P4_LS2QgQNU&feature=related I completed the small experiment. thanks to all who made an attempt to help.

    I must assume you are talking about pins 2,6,7 on the 555 Timer Chip? It is running in astable mode to produce the frequency used for the experiment.

    This link shows the different circuits and formulas for calculating frequency:
