Beginners *DO* manage to blow semiconductors, usually in ways experienced techs don't expect, *BECAUSE* they are experienced and avoiding exceeding datasheet Abs. Max. limits has become almost instinctual to them. Fortunately the better brands of Arduino Uno (clone) starter kits have socketed ATMega328P chips, so as I said above, buying a spare chip, either preprogrammed with the Arduino bootloader or 'factory fresh', then programming it yourself as soon as you can, can save you hours, days or even weeks of frustration. See
https://www.arduino.cc/en/Tutorial/BuiltInExamples/ArduinoToBreadboardN.B. you'll also need a 16MHz crystal and a couple of load capacitors for it (as per tutorial) , otherwise the first time you program the fuses to use an external clock source will lock you out, until you can put that ATMega328P in a board with a functioning crystal or external clock.Since I posted in this topic back in 2017, I've treated myself to Elegoo's Arduino Mega 2560 'Most Complete' starter kit:
https://www.elegoo.com/collections/mega-2560-starter-kits/products/elegoo-mega-2560-the-most-complete-starter-kitand also their 37 in 1 sensor modules kit:
https://www.elegoo.com/collections/electronic-component-kits/products/elegoo-37-in-1-sensor-kitbecause I wanted extras of some of the modules, and it saved me much time that would have been wasted sourcing them individually.
Other things (NOT in the kit) I recommend are a DC jack to 2x plugs Y cable so you can power the Arduino and the breadboard 5V/3.3V regulator module from the 9V PSU simultaneously, and a 6xAA battery holder, either with a DC jack plug lead fitted to it, or with PP3 battery snaps so you can use the Elegoo lead, so you can use cheap dollar store AA alkaline cells rather than expensive PP3 9V batteries. However, note the sustained short circuit current of 6x AA alkalines is *MUCH* higher than that of a PP3, so if you are at all unsure of your circuit that needs an external 9V supply, try it with a PP3 first. If you short a 6x AA battery pack in decent condition, you *WILL* melt/burn something!
My opinion of Elegoo kits is they generally 'do what it says on the tin', with adequate tutorials (although a bit light on theory). I am definitely a satisfied customer.
To help with choosing between their top-end Arduino Uno and Mega2560 kits and also the check what the 37 sensor kit would bring to the table I put together the attached spreadsheet. The *ONLY* significant differences (as of 2020) between their top-end Arduino kits were the Arduino itself, and its protoshield. The code and tutorials for both are freely available on the Elegoo website, so if you want to upgrade from the Uno kit to the Mega2560 (for moah pins!!), you only need to buy a cheap Mega2560 clone + a Mega2560 form factor protoshield. If you have stuck the mini breadboard on the Uno protoshield you'll probably want one of those as well.
Sorry the spreadsheet wont directly help if you are comparing other Arduino kits, but at least its got the packing list of the two top-end Elegoo kits pre-filled, so adding a column for the kit you are considering won't take tooooo loooong . . .
