Simple & Cheap Arduino FM Radio! - Tutorial + Code

[@Tumerboy1]

I'm not a programmer, and have toyed with my arduino for a while now. I started working on a TEA5767 radio last year, and was never able to get it to work very well. Part of the problem is that all of the available tutorials include all sorts of extra stuff in their code to turn on auto-searching and such. Your code was exactly what I needed. It was simple enough to follow along, and did what I wanted it to do. I got it working with a rotary encoder and a volt meter I have for this exact purpose. Thank you very much!

The guy that you got some of the code from - Simon Monk - is an author of quite a few books on electronics. My local library had some of his books available to borrow. Nice video, Kevin!

[@Kevindarrah]

thanks, yea I think I'm going to pick up the one he mentioned on that page " Programming Arduino Next Steps"

[@maxsnts]

Not to be pedantic about it, but usually while maintaining states in code its more readable to use "current" instead of "old", so you would have "currentFrequency" instead if "oldFrequency". In complex code it helps a lot.

Hey Kevin, that looks like a fun (FM) board to play with. I'm glad to see another tutorial from you, it has been a while. Have a good and safe Christmas (or insert holiday of choice here).

Thanks for this video, I will be building it. Love in the future to see a Dab/digital version with a lot of presets and a big led channel information display. Just a thought from the UK.

In my case I was unable to find a replacement for my failed remote to my stereo a few years ago, so I bought my first Arduino, lifted the IR LED from the old remote and made one. Cool project by the way Kevin! I like your idea of using an encoder on the tuning, think it would be fun to swap out the potentiometer on the amplifier board with a digital IC, then you could control the entire project via software. Have fun! - Bill

[@Kevindarrah]

good ideas! thanks

[@ExStaticBass]

Interesting project. I would never have considered using an arduino for this before now. Using some warm white LEDs to illuminate the meter would be a nice touch if your going for the old looking theme. I'm eager to see how you put this together in a finished project.

[@marhar2]

I am so glad you said that about buying random things off ebay!

[@BuildItnow]

it's good to know that someone else buys random boards on impulse 😂

[@malenottinicco]

Build It

[@BuildItnow]

Niccolò Malenotti yes?

[@TekkGnostic]

Drinking and ebay has resulted in some interesting purchases for me. Have a stockpile of hundreds of components I might ever use 1 of.

[@legolas199]

Would this work with an arduino mini? I'm new to this and what is really confusing me is how to add a tuner dial to the radio for seeking stations. You know like a digital swivel button of some kind to browse through the stations. What is that called, and how do I add it to the mini with a radio board? Any help is appreciated!

[@Emtron_Technologies]

Very Nice. I will build this kit and i'm planning to add an LCD & Rotary Encoder( for enhancements)..

[@nomadic_rider42]

Love the Pinout of 328 breakout. Could you please tell us how you designed it?

[@n0ukf]

I'm looking for any HD radio chip on a breakout board. So far I can only find the bare chips (I can't do SMD) off boards or the analog radio chips on boards.

[@gschultz2010]

Kevin Was interested in your project to tell if your garage door was open... cant seem to find it again.... can you give me a hint to where i can find it again

[@Kevindarrah]

yea, should be cheap and easy WiFi part 1

[@TheJuanditas]

if i want to do a am radio, will be the same?

[@vlad-j4m]

dunno my 15w amp kits turned out great. surprisingly

[@smartydix]

Any way to expand the frequency range of the fm board? :)

[@EmilFihlman]

Is your code erroneous? To low pass filter one does loop(accumulator+=read). You do loop(accumulator=read).

[@EmilFihlman]

Oh you explained it afterwards.

[@yassineenissay6225]

Please i need your help my project it concerns to make a calcukatrice a commands vocales if you have ideas And thank you for your project

[@xennelul]

How about station memory?

[@Kevindarrah]

yea, and I think I'm going to add a real time clock, so that it can be like a clock radio...

[@xennelul]

Cool project!! Thanks for being so inspiring!

[@kieran_hammond]

Anyone know of a good way of drawing custom meter scales?

[@yngvenystrand167]

You might want to take a look at Galva www.f5bu.fr/wp/?page_id=13

[@doublebulbing]

now if it would only do HD radio

[@НиколаНиколов-м1л]

nice vid :)

[@letmexplainyou]

ROFL! If this is simple...
