If you mean that the power resistor heater is not turning off, double check your wiring and the pinout of your MOSFET. Agree about the gate resistor.
I read serial values and can see that the pot is working. If that is a problem, a 10K.

Triple check the wiring irzf34n post a circuit diagram hand drawn, not Fritzing. The test code I used is here. The key specification is the value of Vgs quoted in the on-resistance section. I am using the attached circuit to heat up the 3D printer bed. I measured a 2. It sends sine wave: Screen Shot at A better choice would be more like ohms, high enough to limit current but low enough to charge the input capacitance quickly as possible.
Ok, once again, thanks for helping out an electrically challenged person. Is your printer bed rotating? Please point out what you are calling a thermistor on your diagram. But that didnt make a difference.
MarkT Brattain Member Posts: Also the sine wave code is something I found out on one of the forums that was used to demo a bulb going dim datssheet bright slowly.
This is one of many useful ones. The behavior that you describe sounds like what jremington mentioned in reply 7. I need to study more. Attached is the new circuit just a dafasheet to my prev, this time using a pot. Normally the on-voltage will be about 3 times the threshold voltage being the point the device switches fully off.
I tried at reducing the resistor from 10K to Ohm.
So the heater can be on during reset until the pin 3 pinMode is executed in setup. But the thermistor isnt turning off.

I did connect a 10K from the gate to the ground. What I noticed is that when i disconnect the 19V supply, the serial monitor shows a steady 0 from the vatasheet read from A0. Here is the code, Code: The gate resitor is way too high. I am PWMing the pin 3 of the nano. Is the attached looking any better?
But when I connect the 19V, the values start floating wildly, and thats probably why the thermistor started smoking before I unplugged. A thermistor is a type of variable resistor used to measure temperature. The thermistor 25W 5. IRFZ34N getting too hot.

As mentioned above, the schematic shows the Datsheet wired backwards, dxtasheet can’t work the heater should be on all the time due to the body diode. In between those two the device can be half-on, meaning it may dissipate lots of power and get very hot – the region of operation you want to avoid. Some people get confused by the threshold voltage – this is the voltage the device switches fully off, not on.
