Class to get you started

The set that I have received has been delivered with the customary speed.
Everything complete.
Ardunio Board is an original.

The set offers a great introduction to the fundamental understanding of working with .mu.C's.
The enclosed booklet has actually been translated from English into German relatively poor, but this is not further disturbing.
The example circuits work quite well so far, but the enclosed electric motor and the power are not suitable for operation on the Arduino board as they require more power than can supply pins.

I do not know whether that is so in all sets, or only my, but the motor draws about 200mA at idle but with a bit of trial and error and the use of the enclosed transistor + external power source, you can still bring him to run.
Another shortcoming in the engine were the cable which broke away after a short time by himself, but who is in possession of a soldering iron should not interfere with.

The servo I had similar problems, I got the power consumption not measured well this did not move while he was connected to the pins of the Arduino. But again, the solution had an external power source in the form of two AAA batteries. Here, the whole circuit is also technically easier, as a transistor is not needed.

The two transistors are the way to P2N2222A - transistors.

Here again a short list of the delivery and a few positive (+) or negative (-) Notes:

Arduino Uno board:
(+) Original Board

USB cable:
(+) Well cable stop

Jumper cables:
(+) All full by contact. No Problem

Shift register (SN74HC595N of Texas Instruments):
(+) Works

Electric motor:
(+) Works
(-) Cable badly connected and dissolve easily
(-) Can deliver more power than the pins on the Arduino Requires

Servo (Mini servo: Vilros SG90):
(+) Works
Requires can (apparently) deliver more power than the pins on the Arduino - ()

Relay:
() Not tested

Laboratory breadboard:
(+) Works, but a little small so it can be confusing for some circuits (especially in the circuit to the shift register). Perhaps we should be yet another dazubestellen if you want to put more complex circuits.

Temperature sensor:
(+) Works

Photoresistor:
(+) Works

Transistors (P2N2222A):
(+) Funktioneren
(+) Good all transistors

LEDs / RGB Led:
(+) All function

10k potentiometer:
(+) Works
(-) Which bend easily Something thin legs

Piezo buzzer:
(+) Works

Pushbutton:
(+) Functioning

Resistors (both 330R and 10kR with 5% tolerance and 1 / 6W maximum power dissipation):
(+) All I've ever used are fine
(-) Thin legs

Despite a few shortcomings, I would recommend this set yet, for beginners like me just a great overall package.
