    Hi all

    I would like to make a control relay switch on and off 3 times, once per second, then wait until the circuit is reset before doing the same again.

    I have basic electronics skills but not messed with timers etc before

    So bacially when energised the circuit should wait 1 second then energise the relay 3 times in 3 seconds then stop untill the circuit is reset by re-powering the circuit.

    Any ideas if or how this could be done please?

    I can measure the relay resistance if required.

    Simple seqeuncing like that is often done here on the forum using a 555 timer IC (as an oscillator) and a 4017 IC (as a simple sequencer). You could serach the forum for "555 and 4017" or "4017 sequencer".

    I think using a variation on that theme you could make 3 pulses for 3 seconds then stop.
