Hi to everybody, I am building a quadcopter with arduino but I have a problem. when I connect the battery, the engine and the receiver to the ESC nothing happends and the voltage of the battery go down to zero, do you think is a problem of the battery or of the receiver?

I want to say also that some days ago the Esc and the motors were functioning but some times while accellerating they turned off witout any reason, so I did the  wiring connection again but now nothing is working.

I also want to say that i took the receiver from an old RC plane

wires are ok

any help? 

thank you very much

Can You help me? I'm not english, so my english in not perfect, i Just need help for the quadcopter, i don't want to Argue With anybody.
Anyway cool! I will Begin soon my master, i will do a master in space engineering

Let's start over, shall we?
(I tried to delete all the unhelpful posts.)
To everyone: keep it civil and help or ignore.
Thanks!

Ok i deleted everything, thank You very Much, in Italy universities are too theorical, so i try to Learn pratical things by myself.
I explain better the problem: In order to save money i used an Rc receiver and transmitter taken from an old Rc plane, so I don't have the datasheet . I bought the battery on the internet but it has arrived a wrong one. My battery is Lipo 9800mAh but there isn't the discarge rate, so I don't know if it's ok for the Esc. I have Esc 30A, three are opto and one has the Bec, motors are brushless 2213-935 Kv. This afternoon the receiver exploded. So now my question is: how can I choose the right battery and which is the Best transmitter/ receiver to use? Do I Just have to consider the Esc or also the engines? And why can a receiver explode?
Thank You very much

I'm not too experienced in the technical aspects of this hobby, but I can give you a few suggestions on what to look for and what may have possible gone wrong.

Transmitter & receiver:  Although the make & model is not stated, if it came from an airplane and has at least 5 channels and switches for arming and flight modes, it should be OK.

Lipo - if it's a 4S, you may be OK to use those motors but you'll be pushing the limits on the ESCs.  If it's a 6S, you're just going to burn everything up.

Exploding receiver - Spektrum receivers require a voltage of 3.3 and the majority of the rest are designed to run on 5 volts.  If you've connected it directly to your main power supply, that's why it burned up. 

As for your build as a whole - it sounds like you're trying to create a Frankenquad based on your technical knowledge in other areas with little to no research in the functioning of a quadcopter.  You may possibly end up creating a flying death machine of epic proportions.

If, however, you are interested in building a safe, well-flying craft, we'll be more than happy to assist you with a parts list.

Maybe you can provide us some pictures from the part you have and is functional (so not yet exploded).
Then we can look for you if we can make it working for you, and maybe give you a part list for the missing parts.
And maybe if you are lucky someone will make a schematic for you so can follow that.

Give us as many picture so we got a lot of details, that will make it easier for us.

Ok, now i have a Esc 30 A 6 S emax 3 opto and one bec , engine 3 S With recommended a 18 A esc, the battery is 2200 mah 30 c 3 S. Is everything ok now? I have thrown away the old battery.is everything ok? Can I use a 3S motor With a 6S Esc?

Ok, in these days I have studied a bit, now I have a battery 2200 mah 3S 30 C, engine 3s recommended to use With a 18 A esc, and an Esc 6S 30A.
if the Esc 6S can work With an engine 3S everything should be ok, no? And how can I see if the Esc are still working properly?
Do You have and suggestion in parts to cange?

So the motors are 935 KV if i read it correctly.
And yes you can connect the 3S motor with a 6S ESC, they all give the maximum S value, so the ESC can go up to 6S but the motor will not, but you have the correct battery. Do you also already have a flight controller?
Still a few pictures will help us a lot.

I have Arduino uno With Gy 80, pictures coming Except for the battery

So you are going to make your own flight controller with an Arduino.
You already figured out how to connect the ESC to the Arduino and also the receiver.

I found some schematics on the internet, do You have and suggestion?

And, by the way, in the receiver in the Middle do I have to connect the bleack or the Red wires?

If you share the schematics you have found we can look at it.

Without a type and/or picture we don't know what you mean with this: 
"And, by the way, in the receiver in the Middle do I have to connect the bleack or the Red wires?"

The first receiver you blew up.

These are the schematics, are they ok? Actually I don't know why are like this, do You know?

The GY-80 is working correctly
