    Hello, I am looking for help in designing a circuit or circuits that will do the following"

    I will use an Household thermostat (digital) to control the circuit(s). I also have an ac to 6vdc 1,5 amp adapter. When the thrmostat operates (closes circuit) I need it to operate a circuit that will put out a 6vdc pulse for about 1 second. When the thermostat reaches the set temperature and opens the connection, I need this to operate the same or a different circuit, to put out another 6vdc pulse for about 1 second.
    I would appreciate any input as to how this might be accomplished.
    Thank you,

    Look into 555 or 556 (timer IC, single and dual) circuits. They can be configured to do exactly what you've described. I believe it's call a monostable vibrator.
