Thanks a lot, now the circuit works exactly as I wanted! If the circuit is connect as in the picture only 0. Running your Arduino at 5 V this should work ok out to a couple of Amps.

When I connected the gate pin of the transistor directly to the 12V power source the circuit worked as intended and the valve opened.
Sign up using Facebook. I built this circuit as sata of an automatic irrigation system and I am not sure how high the gate voltage should be: The 5 volts seem to be to low to let enough current flow for the valve, which drains around 2. I use a IRF transistor, which might be a rata of an overkill, but it was the smallest I had.
Home Questions Tags Users Unanswered. The arduino outputs 5V which is just over the threshold voltage of V Datasheet: Try your circuit in this form: I learned from another thread here that this makes sense, because a higher gate voltage will let more current flow through the transistor. The LED is to easily see if the valve is open or closed.
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.

lrf3205 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.
