hi, i wanted to use the output voltage (3.5v -3.8v) of a 555 timer circuit to operate a 12v solenoid valve using a mosfet and a 12v 1amp adaptor but i didn't have any output from the drain do you know why?

What Mosfet, did you use a Logic level version?
Is the source common to the 3.3v common?

IRF1010E (mosfet version) the source has the 12v of the adaptor ,what do you mean by this 3.3v?

I meant 3.5v 3.8v
That is not a logic level Mosfet, You need a IRL530 e.g. version.
Low level for the gate to switch.

the IRF1010E datasheet said that the minimum threshold gate voltage is 2v so it can be easily work ok 3.5v - 3.8v

Any logic level FET from the 2n7000 up depending on load and voltage requirements etc.
