I'm new in this site And sorry for my english language..
I need a circuit for my little oven.
I use an incandescent bulb (4x100W) for heating, and I want make a dimmer circuit to change output using a temperature sensor (ptc or ntc).
I have an AC Light Dimmer I want to modify. I want to change the potentiometer to ptc but I can't find a 470k ptc...
What are your ideas for it?
Can I use this circuit?
