Arduino FM Radio project with a Nokia 5110 display and TEA5767 module.

I have built a new, improved version of the FM radio project, which resolves the issues we had in the previous version of the project. The sound quality the project now offers is much better, and it has some new features as well. But first, let's hear it play a YouTube safe song I am broadcasting using this small FM transmitter.

The sound quality is very good in my opinion if we take into consideration that we are using a very inexpensive speaker and amplifier. I replaced the LM386 amplifier module with the PAM8403, and I noticed a huge improvement in the sound quality. The amplifier module offers an embedded potentiometer to control the sound output, so we need one part less. I also replaced the potentiometer I was using to change the frequency of the Radio receiver with a rotary encoder.

This way, the frequency the radio receiver is set is stable, and we also gain a button. I am using the rotary encoder button to turn the backlight of the display on or off.

Another feature I added is that if we leave the Radio Receiver at the same frequency for more than 5 minutes, it will automatically save that frequency to the Arduino EEPROM memory. So, the next time we power up the project, the radio will automatically tune in to the frequency we were listening before. Cool isn't it?

The schematic diagram shown in the video has a small mistake. CLK pin of the display must be connected to D13 and not 3.3V

Cheers!

This project along with the beautiful enclosure is just brilliant. Looks like a very professional product.

Dear Nick, I write to you from Guatemala. I followed the instructions to make the project "Arduino FM Radio # 2" and I have made it work. I just had to do a little research on the 3.5 mm plug that is not described in your video; I also needed to lower the intensity in the code to appreciate the information on the LCD 5110, and rename the libraries; finally, in my case the screen works better with 3.3V (Vcc to 3.3V on the Arduino), the other components work well with 5V. On the other hand where I live there is no need for antenna.

Congratulations for such an interesting project. I think that what you do helps a lot of people to enjoy, learn and take advantage of the moments of rest in interesting matters.

You inspired me to start use Arduino and I discovered that Arduino is very interresting. Thank you!!!

[NM-tobh]

thank you Nick for another great project. I just made this one, and it's working :)

One thing that might help people, is I had to install the Adafruit BusIO library

Brilliant project! The enclosure looks really beautiful!

[MrAtarifreak]

Thanks for the video, I learn a lot from it. I love this project.
Keep up the good work.

Great upgrade to an already awesome project, I'm going to build this even though I don't need it, I already have most of the parts lying around.

Hi Nick - I am glad you swapped pot for rotary encoder as I could not get the frequency to stay stable with the pot. I'm looking forward to trying this. Best wishes.

Really love the enclosure! Your design skills got to pro level :)

[saxhorn]

Looks great. I built the first version but wasn’t happy with the sound. I’ll give this one a try, especially since I have since bought a 3D printer and love your Art Deco enclosure. I live in Long Beach, California - a very Art Deco city.

Hi, I used your code and connected everything properly, but the only thing that can be seen on the screen is FM Radio, I used version 2 of yours so it doesn't work for me, what do I haveDone wrong ?

[eddiejones]

Great Video. I have been looking for something like this for my grandson, who is 8. This will make a great project for he and I to work on together.
Thanks Again....

Your videos are great and I believe I've seen ALL of them. While I appreciate your time and dedication to the channel, I don't understand the value proposition of making pretty much all of them under 10 min... Sometimes it would be great to have you speaking a little slower and explaining things in more details. If anything to improve: slow down :-)

[nzseagull]

Nick thanks heaps your videos they are very professional love all your projects you have been a great help Thank you ;-)

[adrianglezmahe]

Amazing project.
It works perfectly !

[amgmg]

Thanks, great quality videos on your channel.
Are you a Spaniard?

[TactlessWookie]

I love it. Terrific project. I just may have to make and print one.

[mechlopak]

Good job ! With greeting from Poland !!! :)

I really enjoyed watching you build this project and I'm going to buy the same complaints for a tub radio up-cycle project that I'm planning. I want to know if it would be possible to incorporate bluetooth into this project to allow playing music from your phone and listening to FM radio?
