YouTuber's clock

Are You always curios how many subscribers You have on Your YouTube channel? Me too, so I have made this YouTuber's clock! If You have one You don't have to smash F5 button so often.

You will need:

• WeMos D1 Mini
• 8-digit 7 segment screen

D1 mini WiFi ESP8266 pinout:

• D8 - DataIn
• D7 - LOAD/CS
• D6 - CLK

It has been designed for 8-digit 7 segment screen controlled by MAX7219.

It should work on boards with ESP8266 module, but I have tested it only on D1 mini clone. If You use another board You may need to change the pinout.

There is only a few delays used at the beginning of the code. I have programmed it using timers (especially in animations) so this code supports multitasking. With this, You can easily add a new functions running in background etc.

You can watch build tutorial here: It's in Polish language but it should be easy to follow.

If You like this project consider supporting me here.

Features:

• Multitasking ready
• Auto DST switch
• Randomly chosen animations
• Shows time, actual date, Your subscription and views count
• Time synchronized with NTP server
• WiFi Manager - You can easily change Wifi SSID & password without reprogramming Your board

Needed libraries:

You can download these libraries from library manager in Arduino IDE:

• NTPClient
• Time
• YoutubeApi
• WiFiManager
• LedControl
• ArduinoJson (Version 5.13.5 - It won't compile on newer versions)
• ESP8266 (from Boards Manager. You need to add this URL:http://arduino.esp8266.com/stable/package_esp8266com_index.json first in Arduino IDE preferences -> Additional Boards Manager URLs. Then You will find ESP8266 in Boards Manager)

You need to download these libraries from github and put in Your Arduino libraries folder.

• Timezone
• SimpleTimer

If You get a compilation error related to avr/pgmspace.h, You need to change this line:

#include <avr/pgmspace.h>

in \libraries\LedControl\src\LedControl.h (Which should be located in your Arduino libraries folder)

To this part of the code:

#if (defined(AVR))
#include <avr\pgmspace.h>
#else
#include <pgmspace.h>
#endif

You can find me on:

• YouTube
• Facebook
• FB Group
• Instagram
• Thingiverse
