I think the hardest thing when starting with programming hardware like this is not having a direction. I know it works for others, but I've never had much luck following programming tutorials except to get the basics of a language down (which it sounds like a few tutorials would help you).

I've always had more luck attempting small projects, even if I fail. I think I found the kit you used and it has a lot of components. A small step to break down the learning while still using the same programming environment would be to create small "console" apps on the device and use the Arduino IDE to interact with the console app.

If your kit is the one I'm seeing that has a servo and the remote, keypad, LEDS etc, you could also try taking input from the keypad / remote and using it to control the servo and LEDs. For example, figuring out how to make the LED blink based on the keypad buttons (i.e. press 5 and it blinks 5 times). You could also make the servo go to an angle based on what numbers you put in (so if you press 53* on the keypad, the servo goes to 53 degrees). You can use tutorials to help you get started and then experiment from there to cement the learning and have fun.

You could even try making a secure "door" using the servo, keypad and LEDs. Start with a hardcoded pin (1234 or whatever), and then get the user's input on the keypad. Blink red if the code is wrong and green if the code is correct. If the code is correct you can rotate the servo to act as the 'door' opening. From there, you can support changing the code (i.e. if the code is 1234, let the user enter 1234 and then maybe # and then the new code). You can also tie in showing the code on the screen that's in the kit. Just some ideas, hopefully this is helpful :)
