I measured a 2. But the thermistor isnt turning off. Normally the on-voltage will be about 3 times the threshold dahasheet being the point the device switches fully off. MarkT Brattain Member Posts: This is one of many useful ones.

I read serial values and can see that the pot is working. If you mean that the power resistor heater is not turning off, double check your wiring and the pinout of your MOSFET. The test code I used is here.

Agree about the gate resistor. But when I connect the 19V, the values start floating wildly, and thats probably why the thermistor started smoking before I unplugged. What I noticed is that when i disconnect the 19V supply, the serial monitor shows a steady 0 from the pot read from A0.

Is your printer bed rotating? A thermistor is a type of variable resistor used to measure temperature.

It sends sine datashset Attached is the new circuit just a variation to my prev, this time using a pot. Please point out what you are calling a thermistor on your diagram.

But that didnt make a difference. Ok, once again, thanks for helping datasgeet an electrically challenged person. Triple check the wiring and post a circuit diagram hand drawn, not Fritzing.

I am using the attached circuit to heat up the 3D printer bed. If that is a problem, a 10K. I need to study more.

Here is the code, Code: 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. The thermistor 25W 5. I am PWMing the pin 3 of the nano. Also the sine wave code is something I found out on one of the forums that was used to demo a bulb going dim and bright slowly. The key specification is the value of Vgs quoted in the on-resistance section.

I tried at reducing the resistor from 10K to Ohm. The behavior that you describe sounds like what jremington mentioned in reply 7.

IRFZ34N getting too hot. As urfz34n above, the schematic shows the MOSFET wired backwards, which can’t work the heater should be on all the time due to the body diode.

The gate resitor is way too high. Screen Shot at So the heater can be on during adtasheet until the pin 3 pinMode is executed in setup. A better choice would be more like ohms, high enough to limit current but low enough to charge the input capacitance quickly as possible.
