Mark has a thing with Audio Analyzers: "They are simply fun to look at. Patterns moving up and down to the music. Amazing. On my private channel, called The Electronic Engineer, I published dozens of analyzers. I also did a few for element 14 like a web-based analyzer and another one made of Lego bricks."

In this episode of element14 presents Mark builds a new backdrop item, a Smart Youtube Counter with Audio Analyzer.

Watch the Video:

https://youtu.be/1WrkDMRLRGg

So, with my mind set for analyzers, I just had to include one when I designed this YouTube subscriber counter and the result is amazing. I am very pleased with the outcome:

YouTube subscriber counter
Playback of audio files for new subscribers
Possibility to program different sounds for milestones.
It’s connected to the internet using WIFI, so adding a clock or a messenger service is technically possible
Audio analyzer displaying FFT results of the audio.
Microphone input!

Components and Parts:

Although the number of components is only a few, I did design a PCB. You can order your own (check out the part list). The PCB production files are included.

Take note when assembling the PCB, not all components are required. I added two row headers only for the purpose to have the pins available if I need those. No need to actually assemble those headers. Same goes for connector H9, you only need it if you decide to use a microphone on a wire.

Programming

If you are using the designed PCB, programming the firmware is easy. The only things you need to change is your WIFi credentials and the info to your youtube channel.

The author of the specific library that is used made a nice tutorial on how to do that:

https://github.com/witnessmenow/arduino-youtube-api

One important thing that is not shown in the video:

You need to upload the mp3 files from the data folder to the Arduino internal storage.

To do so you have to select the ESP32 Sketch Data upload function from the Tools Menu in Arduino IDE

A Smart Youtube Counter With An Audio Analyzer - Episode - 658

vijeth_ds — Fri, 12 Jul 2024 13:13:38 GMT

Revision 4 posted to Documents by vijeth_ds on 7/12/2024 1:13:38 PM

In this episode of element14 presents Mark builds a new backdrop item, a Smart Youtube Counter with Audio Analyzer.

Watch the Video:

https://youtu.be/1WrkDMRLRGg

So, with my mind set for analyzers, I just had to include one when I designed this YouTube subscriber counter and the result is amazing. I am very pleased with the outcome:

YouTube subscriber counter
Playback of audio files for new subscribers
Possibility to program different sounds for milestones.
It’s connected to the internet using WIFI, so adding a clock or a messenger service is technically possible
Audio analyzer displaying FFT results of the audio.
Microphone input!

Components and Parts:

Although the number of components is only a few, I did design a PCB. You can order your own (check out the part list). The PCB production files are included.

Programming

If you are using the designed PCB, programming the firmware is easy. The only things you need to change is your WIFi credentials and the info to your youtube channel.

The author of the specific library that is used made a nice tutorial on how to do that:

https://github.com/witnessmenow/arduino-youtube-api

One important thing that is not shown in the video:

You need to upload the mp3 files from the data folder to the Arduino internal storage.

To do so you have to select the ESP32 Sketch Data upload function from the Tools Menu in Arduino IDE

Mark's revamped roulette wheel, devoid of its original cheat mode, embodies a blend of nostalgia and modern design. The ESP32-driven functionality, coupled with an enhanced LED display and audio capabilities, elevates the gaming experience. Whether it's for family game nights or a trip down memory lane, Mark's creation stands as a testament to the enduring appeal of DIY electronics and the joy of reinventing childhood treasures.

A Smart Youtube Counter With An Audio Analyzer -- Episode-658

Revision 1 posted to Documents by e14phil on 7/10/2024 11:41:38 AM

So, I have this thing with Audio Analyzers: It’s simply fun to look at. Patterns moving up and down to the music. Amazing. On my private channel, called The Electronic Engineer, I published dozens of analyzers. I also did a few for element 14 like a web-based analyzer and another one made of Lego bricks.

Watch the Video:

So, with my mind set for analyzers, I just had to include one when I designed this YouTube subscriber counter and the result is amazing. I am very pleased with the outcome:
