I'm making a solenoid motor with a n-channel logic MOSFET to operate the solenoid. I'm having trouble controlling the MOSFET gate, which needs to be adjustable between about 4 to 15 Hz to turn the motor flywheel. I've used a 555 as an astable but it doesn't switch the MOSFET. Any help would be very useful. Thanks.
