  • 555 Timer Circuits

    I am looking for a 555 timer circuit that will drive a relay and/or a coil directly.

    I would like to be able to adjust the on and off time seperately so that the amount of on time and the amount of off time are different amounts....

    Is this possible?

    Thank you for any and all help with this.....

    Hopes and Dreams....
