Re: The best way to drive a heating element?
Here is an of the shelf solution that might work for you if you are going to use it for 5 volts or 3 volts you will need to change the resistor to the optic sensors for it to work correctly
If I remember correctly it is setup for a 12 volt input system

Another option might be to use this module might be a simpler method of doing what you are trying to do

You might get a module that does not work correctly meaning that you can not get the current all the way down to the milliamperes range just try another module I have had this issue with a couple of these modules but most of them do work correctly
