亲爱的朋友们，欢迎观看另一个Arduino项目视频！
在这段视频中，我们将构建一个改进版的Arduino调频广播(FM)项目。
有很多事情要做，所以我们开始吧!
大家好，我是尼克，欢迎来到Educh8s.tv，这是一个关于DIY电子产品的频道。
项目
在这个视频中，我分享了我为帮助你开发类似的项目所做的一切。

几个月前，我用TEA5767(收音机模块)在一个面包板上建造了我的第一个调频广播项目
调频收音机模块
 
这个项目工作得很不错，但有一些问题。
如你所见，我已经建立了一个新的改进版的调频广播项目，它解决了
我们在以前版本的项目中遇到的问题

English: 
Dear friends welcome to another Arduino project
video!
In this video, we are going to build an improved
version of the Arduino FM radio project.
There is a lot to cover so let’s get started!
Hello, guys, I am Nick and welcome to educ8s.tv
a channel that is all about DIY electronics
projects.
In this channel, I share everything about
the projects I build to help you develop similar
projects or inspire you to start making things
because it is easy, fun and creative.
Subscribe to the channel now if you do not
want to miss any future video.
A few months back I built my first FM radio
project on a breadboard using the TEA5767
FM radio module.
The project works great, but it has some issues.
You can watch that project video by clicking
on the card here.
As you can see 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.

Chinese: 
这个项目现在提供的音质要好得多，而且也有有一些新的特点。
但首先，让我们听到它播放YouTube安全歌曲，我用这个小广播
调频发射机
在我看来，音质很好，如果我们考虑到我们是
使用非常便宜的扬声器和放大器。
我把LM386放大器模块换成了PAM8403，我注意到有了很大的改进
在音质上。
放大器模块提供了一个嵌入式电位计来控制声音输出，所以我们需要一个
少的部分。
我还更换了我用来改变无线电接收器频率的电位计。
带旋转编码器。

English: 
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.

Chinese: 
这样，无线电接收器设置的频率是稳定的，我们还可以使用一个按钮。
我使用旋转编码器按钮打开或关闭显示器的背光。
我补充的另一个特点是，如果我们将无线电接收器保持在同一频率，
超过5分钟，它将自动将该频率保存到Arduino EEPROM以供
记忆。
因此，下次我们启动项目时，收音机将自动调到
我们以前听过的频率。
是不是很酷呢？
除此之外，我还更改了信息在Nokia 5110(显示屏)上的显示方式。
我已经加载了一个自定义的艺术装饰风格字体来显示频率，我删除了一些
因为我想让它看起来干净
我将很快发布视频，向您展示如何将您喜欢的任何字体加载到Nokia 5110显示屏上
真是太酷了！
现在让我们看看构建这个项目所需的部分。
所需部件如下：•Arduino Nano × 1
•TEA5767调频收音机模块 × 1
• Nokia 5110液晶显示屏 × 1

English: 
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?
In addition to that, I changed the way the
information is displayed on the Nokia 5110
LCD.
I have loaded a custom Art Deco style font
to display the frequency, and I removed some
information from it because I wanted it to
look clean.
I will publish video soon to show you how
to load any font you like to the Nokia 5110
display; it is so cool!
Now let’s see the parts needed in order
to build this project.
The parts needed are the following:
• An Arduino Nano
• A TEA5767 FM Radio module
• A Nokia 5110 LCD display

English: 
• A rotary encoder
• A PAM8403 Amplifier module with an embedded
potentiometer
• A small 3W speaker
• A breadboard
• Some wires
The total cost of the project is around 20$.
You can find links to all the parts I am using
in the description of the video below.
Before attempting to build this project, be
sure to watch the video of the first FM radio
project.
It will help you better understand this, more
advanced project.
Now, all we have to do is to connect all the
parts together according to this schematic
diagram.
You can find a link to the schematic diagram
in the description of the video below.
The amplifier module has two audio inputs
and two audio outputs.
We connect the sound output of the FM radio
module to the amplifier module and the output
of the amplifier module to the speakers.
In this project, I am using only one speaker,
so I am going to connect only the right channel
of the sound output of the radio module to
the right input of the amplifier module.
Lastly, the right channel output of the amplifier
module is connected to the speaker.
Of course, don’t forget to connect the amplifier
module to power via these pins here.

Chinese: 
• 旋转编码器 × 1
•带嵌入式PAM8403放大器模块 × 1
•一个小型3W扬声器 × 1
•面包板 × 1
•一些电线
该项目的总成本约为20美元。
你可以在下面的视频描述中找到我正在使用的所有部分的链接。
在尝试建立这个项目之前，一定要看第一台调频收音机的视频
项目
它将帮助您更好地理解这个更高级的项目。
现在，我们要做的就是根据这个示意图把所有的部件连接在一起。
您可以在下面的视频描述中找到指向示意图的链接。
放大器模块有两个音频输入和两个音频输出。
我们将调频收音机模块的声音输出连接到放大器模块和输出
将放大器模块连接到扬声器。
在这个项目中，我只使用一个扬声器，所以我只将收音机模块
声音输出的右声道连接到放大器模块的右输入。
最后，放大器模块的右声道输出连接到扬声器。
当然，不要忘了通过这些插脚将放大器模块连接到电源上。

English: 
Now that we have connected all the parts let’s
power up the project to see how it works.
As you can see, the project welcomes us with
a splash screen for three seconds and then
reads from the EEPROM memory the saved frequency
we were using before.
The project works fine, the frequency knob
changes the frequency, this potentiometer
increases or decreases the volume of the sound
and if we press the button of the rotary encoder,
we can enable or disable the backlight of
the display.
Let’s now go to the computer to take a quick
look at the software side of the project.As
you can see we are using a lot of libraries
in this project.
As always you can find links to all the required
libraries in the description below.
The code is more complex than most of the
projects we have built so far so I won’t
try to explain it in a short video.
I tried to make it a simple as possible with
easy to read and to understand functions.
The basic idea is this: If the rotary encoder
shaft has changed position and has stayed
in the same position for more than 1 second
we need to set that frequency to the FM Radio
module.

Chinese: 
既然我们已经连接了所有的部分，那么让我们打开项目的电源，看看它是如何工作的。
正如你所看到的，这个项目用3秒钟的闪屏欢迎我们，然后
从EEPROM存储器中读取我们以前使用的保存频率。
项目工作正常，频率旋钮改变频率，这个电位器
增大或减小声音的音量，如果我们按下旋转编码器的按钮，
我们可以启用或禁用显示器的背光。
现在让我们到计算机上快速查看项目的软件部分。
您可以看到我们在这个项目中使用了很多库。
和往常一样，您可以在下面的描述中找到所有所需库的链接。
代码比我们迄今为止所构建的大多数项目都要复杂，所以我不会
试图用一个简短的视频来解释它。
我试图使它尽可能简单易读和理解功能。
基本思想是：如果旋转编码器轴改变了位置并保持不变
在同一位置超过1秒，我们需要将该频率设置为调频收音机模块

Chinese: 
调频收音机模块需要1秒钟左右才能调到新频率，所以我们不能
改变每个旋转编码器上的频率变化，因为这样频率就变化得
会非常慢。
当新的频率被设置到模块时，我们计算从那以后经过了多少秒。
设置了频率
如果时间超过5分钟标记，我们将该频率保存到EEPROM内存中。
您可以在下面描述的链接中找到此项目的代码。
现在电子设备已经准备好了，我可以通过3D打印一个外壳来完成这个项目。
它将电子设备移动到一个小型的电路板上。
我已经为它设计了一个基于旧收音机的装饰艺术外壳。
我已经将文件上载到Thinggiverse，以便您可以立即开始3D打印。
如果你愿意的话。
我将用木丝3D打印这个外壳，并在一切就绪后发布一个新的视频。
 
我很想听听你对这个调频广播项目的看法。
另外，你喜欢我为它设计的外壳吗？
请在下面的评论部分发表您的评论和想法。

English: 
The FM radio module needs around 1 second
to tune in to the new frequency so we can’t
change the frequency on each rotary encoder
change because this way, the frequency change
will be very slow.
When the new frequency is set to the module,
we count how many seconds have passed since
the frequency was set.
If the time exceeds the 5-minute mark, we
save that frequency to the EEPROM memory.
You can find the code of this project in a
link in the description below.
Now that the electronics are ready I can complete
this project by 3d printing an enclosure for
it and moving the electronics to a small prototyping
board.
I have already designed an Art Deco enclosure
for it based on an old Radio.
I have already uploaded the files to Thingiverse
so that you can start 3D printing it at once
if you wish.
I am going to 3D print this enclosure using
wood filament and publish a new video when
everything is ready.
I would love to hear your opinion about this
FM Radio project.
Do you like the improvements I made to it?
Also, do you like the enclosure I designed
for it?
