To control the output power of a heating element. I'm using a variable solid state relay. This SSR can be controlled with a potentiometer of 500Kohm to control the output power.
Now i want to replace the manual potentiometer with something I can program with arduino. I was thinking about a digital potentiometer (digipot). I already tried this with the AD5206 100Kohm digipot. It has 6 channels each with a resistance of 100Kohm. I tried to put 5 channels in serie. But didn't manage to get this to work.
Is this the way to go? Or are there other more simple sollutions?
