    hi
    i have a little theoretical project where i have 2 relays (1x 1min relay, 1x 20min relay). 1 start button, 1 stop button and a fan. i need to press the start button and the fan runs for 1minute then off for 20minutes then starts again for 1minute and continues looping till the stop button is pressed. i would welcome any help with a hard wiring diagram.

    in short, you're asking for a schematic for an astable circuit that could operate as what you have describe. a 555 timer can do that for you which i believe is the simplest approach.

    i believe a circuit for that has already been posted here in the forum. pls do some research.
