hello to everybody,
can somebody help me,
how to connect audio output to adc
i have a rado tuner,
i just need to connect audio output to adc after to connect to arduino
thnx

What do you mean connect audio output to ADC? ADC is an input .

You need to put a little more effort into your post. You can help others to help you by providing more details and writing in a way that makes you text understandable. Please use a capital letter at the beginning of a sentence and a period at the end.

Exactly what kind of help do you need? You need to show your work. Where is your schematic? here is your code?

Generally speaking. Red wire to A0 on Uno. Black wire to ground. Will probably fry Uno, but hey, they are cheap.

Also. Uno ADC only reads voltages from 0 to 5 volts. So. If any of the audio output is less than 0 volts, it will be lost. If any of the audio output is more than 5 volts, it will be lost too.

Therefore. Step 1. Figure out the range of voltages present in the audio ouput of your radio tuner. You are looking for maximum voltage and minimum voltage.

Do you have the datasheet for the tuner?
Is the 'audio out' a standard line-level output intended to feed an amplifier, or is it speaker terminals?

what he said.
if you can use Line Out, that would be good since those are usually 1 volt peak to peak.

no is an audio ouput but i can amplify the signals

no is audio output, but i can amplify the signal ,after i thougt to conect to arduino,

Once you have the signal converted to digital, what will you do with it? This may have a bearing on how simple/complex the circuit needs to be to interface the radio to the ADC input for best effect.

after to convert to dac after to programming arduino and also to connected to speaker to hear the radio, just to learn hobby

How will a digital conversion of an audio signal be used to 'program' the Arduino? Is it just to switch on some function?
i dont know how to explain, but i read arduino for musician, and he explain audio input, audio output

Step 1.
Minimum and maximum voltages that the ADC will receive?

I realize that English is not your native language. However. You have spent a lot of words. You HAVE NOT provided a single NUMBER. NOT A ONE! I am going to provide a kindness to your and my sanity, and tell you: google it.

Hi michael1978.

ADC = Analog to Digital Converter
DAC = Digital to Analog Converter.
They are oposite to each other.
An ADC is used to convert vaying voltages into digital numbers that can be used in a computer.
A DAC is used to reverse the process.
So, you can say an ADC is a computer input device while a DAC is a computer output device. Does that clear it up for you a bit?

And it would help if you can explain what you actually want to do. I understand language is a barrier, but without knowing your actual use it is very hard to help.

nothing man, i told you here, i want to conect my receiver to arduino, after output to speaker, and to programming, all to do via arduino

Are you trying to make an audio effects generator, where audio in gets modified by the Arduino to produce the required audio output? If so, a simple potentiometer (volume control) plus a DC bias arrangement may be all that's needed to bring the audio input within the ADC input range.

You need to take more than 5 seconds man and describe what you want to do. People are spending their valuable time to help you man but man you are just not taking the time to help them man.

Where is your schematic? Where is your code? Where is the detailed list of what you want to do man?
