Getting started with Arduino

Question

Arduino

1) How difficult is it to write on Arduino?
2) What practical skills do I need to have in order to make the fan work at the right time for me, or, if necessary, lower the temperature (not in terms of programming, but in terms of skills / knowledge of electronics)
3) What resources would you advise to complete the above task, I would like so that everything would be as detailed as possible, because There is plenty of time, but I would not want to burn my first microcontroller.
I'm just a beginner in this business, and I would like to hear decent answers with links to resources, because Google gives out a lot, a lot of water.
Thank you all in advance!!!

Answer 1

1) It depends on what to write. As far as I understand, a modified SI is used there. In your case, a minimum familiarity with the language will suffice.
2) You need to know Ohm's law from physics. Read articles for beginners on easyelectronics
In principle, there are ready-made blocks with temperature sensors, relays, examples of which can be easily found on the net.
3) On ebay, an arduino clone costs 200 rubles. Grab a couple spares and don't be afraid to experiment. You can burn the board, but it forgives some mistakes.

Answer 2

1) writing is not difficult if you get into the essence of the process;)
2) a lot depends on what kind of voltage you are interested in ??? AC-DC???
3) burning the board is actually quite difficult .... there is protection against short circuit - nevertheless, I managed to burn a couple of PWM contacts; ? yadi.sk/d/9ZxZveVRRrA7c mosfet transistor circuit https://yadi.sk/d/BgnBmXc7RrCcV

Answer 3

Check out Ardublock, it's a visual add-on for arduino, it's easy to get started.
To make a 5v cooler work in time, a lot of knowledge is not required, and if you want to power a real fan from 220v, you will need a couple of relays. If you want to do it on time, there is a delay in mi-seconds in arduino or put a thermometer to take readings from it.
These courses helped me a lot in studying: rutracker.org/forum/viewtopic.php?t=4566253
And this emulation (in which I burned more than one virtual LED): 123d.circuits.io
