HI, I am new to arduino, and I would like to control some ventilation using an arduino.
I am confident that I can put up a temp sensor and write a program for a servo or some other kinds of relevant actuation unit, but I am very uncertain of how to implement it with the existing control unit.
I have taken a picture of the component and was hoping that someone could recognise the electronics and give some advise.
On the other side of these electronics is just a turn button which goes from off and then from high to low.
Hope someone can help. Also if you can tell the voltageinvolved. I suspect that it is either 12 or 230v.
I would rather not have at servo control the button, that would look very unprofessional.
