ping(uso) 1.4

---

A table clock and Small connectivity monitor that you can have on your desk.

Disclaimer:

I made this "Connected Thing" for three very simple reasons:

1 - Why not?

2 - I needed to monitor my office connectivity and needed a desk clock.

3 - I couldn't find it to buy. I'm lazy, but when there isn't one, I do it.

Feel free to download and change whatever you want, just don't ask to generate new versions or fix bugs. I don't have time and I did this out of curiosity and fun. Use at your own risk.

Remember: If you used the code, give credit to the author. Whenever possible, buy him a coffee.

Again: Don't insist, I don't have time bro!

Note:

The word "Pingusso" in Brazilian Portuguese means: "It is said of the eyes of someone who has drunk too much alcohol or is very sleepy."

Why and how this thing works:

The code is a simple monitoring tool designed to check internet connectivity using a home WiFi connection. It targets an ESP32 microcontroller board (ESP32-2432s028) and uses a display library, LovyanGFX, to output results on a graphical display.

Key Features:

1. Network Setup and Display:

   • It connects to a specified WiFi network (SSID your_wifi with password <your_pass).
   • NTP (Network Time Protocol) is used for synchronizing the local time with an NTP server.
   • Display components include textual and graphical output using LovyanGFX to show network status, internet reachability, and local time.

2. Ping Checks:

   • It targets various hosts to verify internet connectivity and DNS resolution.
   • Ping.ping() functions are used to check connections to various remote hosts like www.google.com.br, and other DNS resolvers (8.8.8.8 and 208.67.222.222).
   • Checks are also done for specific servers like twitter.com and whatsapp.com.

3. Indicators:

   • LEDs and graphical elements are used to indicate different statuses, like successful connectivity or failures.
   • The graphical display shows real-time status using colors (green for connected and red for errors).

4. Light Detection (LDR):

   • An LDR (Light Dependent Resistor) is connected to an analog input pin to measure light levels and control the screen brightness accordingly.

5. LED Control:

   • The code manages green and red LEDs to visually indicate connectivity statuses.

Flow of Execution:

• Setup:

  • Initializes serial communication, graphical display, and WiFi connection.
  • Outputs network information once connected.

• Loop:

  • Continuously retrieves the local time and displays it.
  • Executes ping checks on the predefined hosts.
  • Controls LEDs based on connectivity status.
  • Uses the LDR sensor to adjust screen brightness.

Libraries Used:

• LovyanGFX for graphical display.
• WiFi and ESP32Ping for network connectivity and ping functionality.

For the love of GOD (whether you believe it or not):

Don't forget to insert the drive for the display in your project: lgfx_ESP32_2432S028.h

This article is fantastic, well, if you don't know Japanese, use Google translator and stop being lazy. You have to want it!
