mosfet as a switch
I am making a board to fire a solenoid which is going to in turn fire a painball gun. I am having a problem with the solenoid not getting enough current though. I was wondering if I was using the MOSFET right. I am using the IRF540 MOSFET to switch on the solenoid. I am using a 10v battery. Coming from the 555 timing chip is 9volts. I hooked the output of the 555 up to the gate of the MOSFET. I hooked the source up to ground. And I hooked the drain up to one side of the solenoid. I can't understand why the solenoid isn't getting enough current because the stock electronics for the paintball gun use a MOSFET just like mine which is rated for almost the same current. The only thing that I can think of is that I'm using the MOSFET wrong. Any help appreciated. Thanks.
