Yes it is very easy, just touch them without having touched ground on a dry day with different fabrics on you and pouf
You can test them easily though: 5v to gate, source to ground 5v to led and 500 resistor to drain should light on the led then ground the gate, should switch it off.
I would try that but I think there's something else going on with my mosfet(more info below)
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Also a picture of your project so we can see your component layout.
Have you checked the value of your 150R resisitor?
Can you post your code?
And I have confirm that with PWM value of 153, the D5 pin is giving about 3.04V. Also yes, my resistor value is around 148.8 ohms
New weird behaviour of the mosfet:
With the circuit configuration above but without plugging in the arduino ground and a little initial push at the motor shaft, my motor spins. The voltage across the motor is about 1.7V-1.8V(which I think explains why it needs a little initial push to start spinning).
With that ground left unplugged, I unplug the wire from D5 and my motor spins slightly faster(voltage across motor is about 2V). If I connect that unplugged D5 wire to ground, my motor decreases speed very very slowly(more than 30 seconds) until the motor voltage reaches 0
Other than that, I realise that, with or without the arduino ground connected, when I put an ammeter between the resistor and the gate like this:
It reads 0 amps
But when I connect the resistor to ground and put the ammeter between it like this:
It reads 15.3mA
That means the the gate isn't drawing any current at any time right? How's that possible if I can manipulate the motor voltage with the wire to D5?
