However I build the exact same project some months ago and used the exact same parts – the same resistances, the same transistor type and the same valve and it worked perfectly with a 5V gate voltage.

The arduino outputs 5V which is just over the threshold voltage of V Datasheet: Email Required, but never shown.
I use a IRF transistor, which might be a bit of dataa overkill, but it was the smallest I had. Looking at the details in the datasheet you need to understand that the V GS is applied between the Gate and source of the N-Channel FET, you can look at Figure 1 to see the switching characteristics.

Thanks dta lot, now the circuit works exactly as I wanted! I suspected the transistor to be broken, but I switched it out several times and the results were the same. Try your circuit in this form: The LED is to easily see if the valve is open or closed.
I built this circuit as part of an automatic irrigation system and I am not sure how high the gate voltage should be: You cannot drive the IRF in the manner shown. When I connected the gate pin of the transistor directly to the 12V power irf32005 the circuit worked as intended and the valve opened. Home Questions Tags Users Unanswered.
