    Blowing things up is easy. Didn't you mean how NOT to blow a bulb? THAT takes skill.

    Please elaborate on your goal so we can help.

    Hi,

    What i meant was that I need the Boe-bot Rev C to run through a series of actions before sending a pulse to a 1.3V filament light bulb attached to the circuit board to light brightly and blow the filament to simulate a blast. I am using the standard 4 x AA batteries battery pack (6V).

    How should I connect the bulb on the circuit board and just sending a 'High PIN' signal will do?

    The light bulb is likely to need more current (briefly) than a Stamp's I/O pin can provide. Look at Nuts and Volts Column #6 (look here) for examples of using switching transistors to control higher currents than a Stamp can provide.
