    Hi,
    I am trying to produce a 1 second pulse with the monostable but for some reason, the output is the inverting of the trigger. The following screenshot explains it all:

    Any help why this is happening to me would be appreciated :)

    Thank you.

    If you need a positive going pulse from the circuit you can put an inverter on the output from the 555. That will give the same polarity as your trigger pulse. :eek:
