I learned from another thread here that this makes sense, because a higher gate voltage will let more current flow through the transistor.
You cannot drive the IRF in the manner shown. 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, dta can look at Figure 1 to see the switching characteristics.
IRF Transistor: correct threshold voltage – Electrical Engineering Stack Exchange
The arduino outputs 5V which is just over the threshold voltage of V Datasheet: Email Required, but never shown. I suspected the transistor to be broken, but I switched it out several times and the results fata the same.

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 LED is to easily see if the valve is open or closed. I use a IRF transistor, which might be a bit of an overkill, but it was the smallest I had.
Thanks a lot, now the circuit works exactly as I wanted! Try your circuit in this form: Sign up or log in Sign up using Google.
I built this circuit as part of an automatic irrigation system and I am not sure how high the gate voltage should be: My basic idea is that if the soil gets to dry the arduino sets the gate voltage, which turns the transistor on and the valve opens.

When I connected the gate pin of the transistor directly to the 12V power source the circuit worked as intended and the valve opened. Post as a guest Name.
