What does a beginner need to work with Arduino?

Question

Arduino

Hey Habr!
In order to learn how to work with Arduino, I want to try to make a device that will connect to a mobile phone via Bluetooth and answer calls (like a headset). Just pick up the phone and that's it.
Now at the stage of ordering components.
In the cart:
1. Bluetooth module HC-05
2. ORduino-Nano 1.1+
3. Solderless breadboard
4. Flexible male-male wires
5. Flexible male-female
wires 6. Flexible female-female wires
7. USB Cable AB
Question is : which of these is not needed? What is worth buying?
I am working with Arduino for the first time.

Answer 1

ORduino-Nano has a mini-USB connector, so USB Cable AB is not suitable for it;)
also, to power the HC-05 module, you need a 3.3 V

Answer 2

1. Find a connection diagram and order parts using it.
Why do mother-mother wires? Although they have a small cost,
I would immediately take a bunch of LEDs + resistances, they are also cheap.
+ A couple of mofet transistors

Answer 3

And I would advise not to use the arduino SDK if possible, as it is very crooked. The same level switching on the leg in arduino is done in 30 cycles, although in fact only 1 is needed.

Answer 4

The board of the arduino itself (I bought "Uno" and "Mega", everything is from the "Chinese"), USB wire, wires of different lengths, LEDs, breadboard, resistors / transistors, 1602nd indicator, ethernet shield, then everything depends on your desire.
I (as a beginner) are here - publikz.com/blog_9659 and publikz.com/blog_3033 . I used it all
. Here I plan (one for a year, the second thing for a couple of months already) to transfer “to a textolite”, but it interferes with the fact that it works completely bug-free.
