Hello.
I built a soldering station based on a PID controller for a Gordak soldering iron. I used a Nokia 5110 LCD as a display. The schematic and the code are attached. The problem is that I tried two times using different IRF530 transistors and the heater of the soldering iron was staying cold. When I used a K1257 or a P55NE06, the soldering station worked normally. I also tried yesterday on a breadboard the entire soldering station and it worked using a IRF630.
Why the soldering station was not able to heat my soldering iron when I was using IRF530 ?
This is the original project: https://www.allaboutcircuits.com/projects/do-it-yourself-soldering-station-with-an-atmega8/
My code: https://pastebin.com/uuDs7ZB0
The schematic is attached.
