What will it take the beginner to work with Arduino?

Hi, Habr!

For the purpose of teaching working with Arduino, I want to try to make a device that will connect to a mobile phone via Bluetooth and answer calls (as headset). Just take the tube and all.

Now at the stage of ordering parts.

In the basket:

1. Bluetooth module HC-05

2. ORduino-Nano 1.1+

3. Solderless breadboard

4. Wire flexible male to male

5. Wire flexible male-female

6. Wire flexible mommy

7. USB Cable A-B


The question is: what is not necessary? What you should buy?

Working with Arduino for the first time.

Solution
on ORduino-Nano connector provided mini-USB, so USB Cable A-B for her will not work ;)
as to power module HC-05 need stabilizer 3.3 In

but the usb power can not be? - jena commented on October 3rd 19 at 02:40
Can. Even the nano is the output power at 3.3 V with built-in stabilizer. - creola.Murray72 commented on October 3rd 19 at 02:43
ie in principle, stabilizator don't have to?
Just as long as they want the path of least resistance to make that easier, and then dig deeper) - jena commented on October 3rd 19 at 02:46
from the USB connected/powered through the mini-USB connector,
but note that the controller ORduino-Nano 1.1+ does not contain a voltage regulator, so you need to feed it regulated 5V supply (from USB or external power). - Dana.Lowe commented on October 3rd 19 at 02:49
Well in the comp if sticking, it's a stable source and did not need the stabiliser? right?) - jena commented on October 3rd 19 at 02:52

1. Download the wiring diagram and order parts
Why wire mommy? Although they cost a little

I'd taken a bunch of LEDs + resistance, they too are cheap.
+ A couple of transistors moveTo
LEDs I also took
And wires, just in case, they cost a bit. They do not need? - jena commented on October 3rd 19 at 02:42
Even the power supply or batteries + charging

If you are not expensive, let them be, it's like a condom better when it is not necessary than when it is necessary but it is not.
Parts needed for a specific schema, if you except it to collect anything you don't, you don't need anything else.

I took myself adruino for "play" and then harder not immediately clear which parts I need, so I found a set of starter kit and ordered all that is there + the fact that inexpensive and can be put in the flow, more. But still, ordered 3 times and still need to order :)

There will always be some sensors, such as temperature, light, humidity... which are not available and the MOSFETs, tomorrow something will come at a greater capacity - creola.Murray72 commented on October 3rd 19 at 02:45
Yes) it is better to err of course. I have a specific goal yet, everything seems to be ordered, and there certainly is unknown, I will power from usb so that the power supply is not needed as such.
Thanks for the reply:) - jena commented on October 3rd 19 at 02:48

And I would advise not to use the SDK Arduino, as it is very crooked. The same switching upravna on foot in an Arduino is 30 clock cycles, but actually only need 1.
I'm just not an expert in electronics, I decided to try. Arduino seems to be the easiest way for beginners or not? - jena commented on October 3rd 19 at 02:44
I did not write anything under Arduino, so I can not say. I just watched the source SDK, and I did not like ) If you are going to do something at the limits of the possible glands — this SDK you just don't fit. - creola.Murray72 commented on October 3rd 19 at 02:47
Understand, but to play enough) - jena commented on October 3rd 19 at 02:50

Charge the Arduino (I bought "UNO" and "Mega", all in "Chinese"), USB wire, wires of different lengths, LEDs, prototyping scarf, resistors/transistors,1602-th indicator, ethernet shield, then it all depends on your desire.

I (as a beginner) here publikz.com/blog_9659 and publikz.com/blog_3033. it's all used

Here's the plan (one — year, the second thing for a couple of months) to move "on the PCB", but is hampered by the fact that works completely bug-free.
Question, if you work specifically for my goals and to be powered by a usb, why do we need resistors/transistors,1602-th indicator, the ethernet shield? - jena commented on October 3rd 19 at 02:46
