Story

This simple tracker will help you to the current situation of different countries due to COVID-19 outbreaks. Also, it will show alternating the current data of different countries of your choice.

The data is collected by the website: www.worldometers.info/coronavirus/

Hardware

M5StickC is a mini M5Stack, powered by ESP32. It is a portable, easy-to-use, open-source, IoT development board. This tiny block is able to create and prototyping any project as your idea.

WiFi Connection

Here you can change your SSID and password.

/*____Wifi _____________________*/
#define WIFI_SSID "JioFi"       // Enter your SSID here
#define WIFI_PASS "Niyast90"    // Enter your WiFi password here

In this, I just added on a few countries. If you can change/add/delete the countries in the main loop of the program according to your interests.

void loop() {
 check_country("India");
 delay(2000);
 check_country("Kuwait");
 delay(2000);  
 check_country("Saudi-Arabia");
 delay(2000); 
 check_country("Qatar");
 delay(2000);
 check_country("US");
 delay(2000);
 check_country("Italy");
 delay(2000); 
 check_country("China");
 delay(2000); 
 check_country("Spain");
 delay(2000);  
}

Note:

Please check the correct names of the needed countries on www.worldometers.info/coronavirus/

Battery Status

The M5StickC has a built-in battery. So I just added to a battery status monitor to understand the battery charge.

void battery_status()
{
  vbat = M5.Axp.GetVbatData() * 1.1 / 1000;
  discharge = M5.Axp.GetIdischargeData() / 2;
  if (vbat >= 4)
  {
    M5.Lcd.pushImage(145, 1, 14, 8, bat_3);
  }
  else if (vbat >= 3.7)
  {
    M5.Lcd.pushImage(145, 1, 14, 8, bat_2);
  }
  else if (vbat < 3.7)
  {
    M5.Lcd.pushImage(145, 1, 14, 8, bat_1);
  }
  else
  {}
  // M5.Lcd.setTextColor(TFT_YELLOW);
  // M5.Lcd.setCursor(140, 12);
  // M5.Lcd.setTextSize(1);
  // M5.Lcd.println(discharge);
}
