    How do I make a circuit that stays connected for 5 minutes, disconnects for 30 seconds, and then reconnects and repeats.
    I am very new to this - sorry!.

    A single 555, with one timing resistor of about 1 meg from V+ to pin 7, 100k from 7 to 6, & cap of 300 μF. Lots of 555 ckts active on Projects now.
