I wonder if anyone can help me here?
I'm shiny new to Arduino and electronics but have several projects on the go to help me learn this magic!
MOSFETS and Transistors... these are complicated (to me anyway) and I was wondering if anyone could provide a good resource for learning what I should be looking for when buying these?
For example, how I calculate the base voltage needed to switch what source voltages etc.
I understand I can use these for switching higher voltages, for example, providing 5v from Arduino to the base and then switching a 12v supply to power LED's for example; but I have no idea how to choose the correct component(s).
I'd really appreciate any advice you could offer.
