Very good kit, but not for beginners (at least with current tutorials)

All arrived quickly with a surprise, RGB LED was mounted backwards, so not usable as suggested in the tutorial. The tutorials until Chapter 12, are well made. But after this is total anarchy. Libraries needed to use digital displays are not provided, it must find and install (just copy them to the "libraries" folder but when we do not know, well we galley). Moreover, this kit lack of a resistance of 1 kOhm and 10 kOhm for all proposed schemes. In addition, for the "keypad", the ports must be shifted relative to the example because we can not use port 1 (tx) for transmitting the data and read key info. If you are in this case, shift the tablecloth and the numbers in the code ...

So for the positive points:
- The card with the selector 3.3V - 5V
- The price.

Cons:
- Not so accessible for a beginner with the provided tutorials (at least those after Chapter 12, but the net contains the best properties)
- The screen solder (and pine are not included ...)
- The two resistors (1kOhm and 10kOhm) missing.
