I want to control a 1 - 10v Booster with my Arduino Uno. I believe I've worked out my programming for the dimming but how do I create the additional circuit? I know there have been already many threads about 0 - 10V where the arduino provides the current, but with 1 - 10 v the arduino has to deal with the current from the Booster. What do I do?
I am an absolute beginner so please do not presume any pre-existing knowledge (Diagrams are always nice!!!).
sorry, I wasn't specific enough, and wrote booster instead of ballast... Apologies.
I'm dimming flourescent tubes with a dimmable ballast. To control the level of brightness you need to control the voltage level between 1 and 10 and the booster/ballast does the rest of the work for the flourescent tubes.
and also is all of the component information on that diagram? i.e. could I use that I can use the diagram to buy all that I need, or do I need more specific information?
Using an op amp is another way of doing thinks but I think that this is simpler.
Just get the stuff for the diagram and use 10 to 12 V. Is the biast isolated? That is make sure there is no direct connection to the mains. If it is you will need an opto isolated transistor to protect your arduino.
