I am completely new to all of this but I need to start getting involved and to build a circuit to perform some functions for me.
I am not sure how far one can develop a Arduino but I have read many confusing pages.
I want to build a control circuit that will control a Dobsonian telescope focuser to enable smooth and slow focusing. Therefore the circuit should have 2 push to make switches to control direction of the stepper motor and a rotary switch to control the number of steps the motor should preform a minute.
Could some one recommend which Arduino I should look at and also what type of stepper motor I should be looking for as there are different types and I do not know what to get.
I am in the UK, what is the best Arduino suppliers?
Thank you for reading
