Walkie-talkie using Arduino, humm.. sounds interesting isn't it?
Alright, lets spend some time today and design and understand this fairly simple circuit, and lets find out how our expectations are challenged by the reality.
Thanks again for checking my post. I hope it helps you.

Instead we can use nrf24l01+pa+l which having better range and connectivity

[@raikishuten3802]

the project itself is not a disaster...probably it just need an audio modulator module or smthing like that....

[@CrazyCoupleDIY]

I wouldb be great full if someone can do that.

@@CrazyCoupleDIY can it work with max4466 microphone and PAM8403 amplifier for speaker

[@MakeAnything-]

My first words were .... DA DA

Ha ha

[@sonalibandre2701]

So the conclusion is to not make one at home, he he

4:40 mins saved, respect

[@TheCalibso]

I was have a plan to do this project, and then I follow your recommendation at the end 😅

[@CrazyCoupleDIY]

Yep, I would not recommend wasting time on this.

[@quincejohnsjr.9431]

Bro stop discouraging people,use a low pass filter at the input setting fc= atleast 500hz to 1khz that way you don't capture any unnecessary High frequency signals remember the adc will only manage to sample recoverable signal when the signal is band limited,then amplify the signal using an external adc sample the signal at a higher sample rate frequency (nyquist theorem) ,i could write a whole book on components that are missing in this project, most importantly filters especially after the DAC (reconstruction filters) question, i didn't know the Arduino nano has a dac and how did you manage to get analog output to directly connect the speaker there? 🤔

[@owendavidmalicsi5900]

it's not dac on the arduino, it's pwm which is why the audio sucks

[@Isaiahbernard.k]

Thanks bro, you saved me alot of time. Also admire your honesty 💯

[@CrazyCoupleDIY]

Glad I could help

[@ayushp.5395]

damn! i was planning to make that but thank god i didn't waste my time!

[@CrazyCoupleDIY]

Happy to help mate

[@Pendu_music_2.0]

How much m and km range this project have and we use ardiuno nano to make

[@CrazyCoupleDIY]

I will not recommend making this
Its complete waste of time

[@Mitrasto22]

And without a screen, how do you know in which broadcast you emit and/or receive?

[@sohailb108]

A more engineering analysis would help a lot. What is the maximum bandwidth of the transmission? What is the minimum required bandwidth for voice transfer? What are other possible solutions?

[@CrazyCoupleDIY]

Absolutely agree
I guess this is just the 1st step towards something amazing.
The config can be changed by updated the variable values in the userconfig.h

[@FuriousVal09]

Yes but where is feeler/antenna (I don't know de name of this object in english) ?

[@learnwithdulinandchanthula1272]

It's not even working
🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬

[@CrazyCoupleDIY]

That's exactly right.
This project is an absolute crap

[@sashanksai2004]

I want to send the voice input via a app so will that be possible

[@CrazyCoupleDIY]

The device you have your app on does it not have wifi.

[@sashanksai2004]

@@CrazyCoupleDIY I want to send voice as output to the speaker outside so will that be possible using my mobile

[@sashanksai2004]

Speaker in the sense a walkie talkie out

Thanks bro
I know I wasted my weekend on this crap

@@CrazyCoupleDIY still i was great video...it ok to fail sometimes, actually It good that you posted the video..Good Luck for your future videos ...

[@CrazyCoupleDIY]

Thanks mate 👍

[@creatvitylight224]

How about add a amplifier to the speaker.. I guess it will also reduce the noise..

[@CrazyCoupleDIY]

Thanks for the suggestion
I already tried that with no luck at all
