Here is the code, Code: I did connect a 10K from the gate to the ground.

The test code I used is here. The thermistor 25W 5.

Normally the on-voltage will be about 3 times the threshold voltage being the point the device switches fully off. I measured a 2.

The key specification is the value of Vgs quoted in the on-resistance section. I read serial values and can see that the pot is working. This is one of many useful ones.

I am using the attached circuit to heat up the datashert printer bed. I need to study more. It sends sine wave: I tried at reducing the resistor from 10K to Ohm. Ok, once again, thanks for helping out an electrically challenged person. But that didnt make a difference.

So the heater can be on during reset until the pin 3 pinMode is executed in setup. Attached is the new circuit just a variation to my prev, this time using a pot.

If you mean that the power resistor heater is not turning off, double check your wiring and the pinout of your MOSFET. The gate resitor is way too high. 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.

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 datahseet.

Please point out what you are calling datashete thermistor on your diagram. Some people get confused by the threshold voltage – this is the voltage the device switches fully off, not on. Triple check the wiring and post a circuit diagram hand drawn, not Fritzing. 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 behavior that you describe sounds like what jremington mentioned in reply 7.


MarkT Brattain Member Posts: A better choice would be more like ohms, high enough to limit current but low enough to charge the input capacitance quickly as possible.

I am PWMing the pin 3 of the nano. What I noticed is that when i disconnect the 19V supply, the serial monitor shows a steady 0 from the pot read from A0. If that is a problem, a 10K. Is the attached looking any better? Is your printer bed rotating?

Agree about the gate resistor. IRFZ34N getting too hot.
