I am trying to make a very simple heating device like that of an electric blanket using 120V. The heater element needs to be adjustable in temperature.
I know basic electronic circuits but I don't know how to easily design electric circuits for an application like this. I realize that the heater wire (aka heater element) simply acts as a fuse when current is introduced. I'm not sure how to change the amount of current in order to change the temperature.
Any help is appreciated.
