Hi everyone,
I've been reading a hell of a lot (almost all tutorial on sparkfun, and now that I found AllAboutCircuits, I'm reading the DC Volume). They all teach you the same basic elements (electricity, ohm's law, voltage divider, serial/parralel communication and so on), and they tell you you can play with IC/Microcontroller to do amazing stuff.
Although I'm starting to see the big picture, I kinda find it hard to fill the gap between these tutorial and how to actually build something real.
I'm assuming that a voltage divider might be used to give the correct voltage to different items on your circuit (like a IC might require a lower voltage that what powers your entire circuit), but how do we actually glue everything together? I mean how do I know if I should use a capacitor in front of an IC to prevent voltage/current variation that would damage it? Is this the kind of info that's available on data sheet of a product?
I'm I missing some tutorial I didn't see?
I have a project in mind, seems relatively simple to me (I'm sure it will be harder that I imagine, but hey, who said it was going to be easy!), I'm homebrewing and I plan on going all electric, as oppose to propane. So I would like to build a controller from which I could monitor, control the temperature and turn on/off the heating elements and pumps depding on certain conditions/data acquired from different sensor (temperature prob, level of liquid in different container, etc). More about all that on another post when I'm a bit more advanced. I started to draw the overall project (high level) so I can actually show something.
Any help / guidance would be greatly appreciated!
