COVID-19 WHO Dashboard

This instructables show how to use ESP8266/ESP32 and LCD to build a COVID-19 situation WHO dashboard.

Step 1: Data Source: WHO Coronavirus Disease (COVID-19) Situation Dashboard

The project data source is come from The World Health Organization (WHO) Coronavirus disease (COVID-19) Situation Dashboard:

https://experience.arcgis.com/experience/685d0ace5...

Step 2: Hardware Preparation

ESP8266/ESP32 Dev Board

Any ESP8266/ESP32 Dev Board should be ok.

LCD Display

Any Arduino_GFX supported LCD is ok, you may find currently supported display at GitHub readme: https://github.com/moononournation/Arduino_GFX

Breadboard

Any breadboard that can fit for the ESP Dev Board and LCD Display.

Jumper Wire

Some Jumper Wires, depends on the dev board and LCD pins layout. In most case 6-9 male to female jumper wires are enough.

Step 3: Hardware Assembly

Push the ESP32 Dev Board on the breadboard and connect LCD with jumper wires.

Here are the sample connection summary:

ESP8266 -> LCD

Vcc     -> Vcc
GND     -> GND
GPIO 15 -> CS
GPIO  5 -> DC (if available)
RST     -> RST
GPIO 14 -> SCK
GPIO 12 -> MISO (optional)
GPIO  4 -> LED (if available)
GPIO 13 -> MOSI / SDA

ESP32 -> LCD

Vcc     -> Vcc
GND     -> GND
GPIO 5  -> CS
GPIO 16 -> DC (if available)
GPIO 17 -> RST
GPIO 18 -> SCK
GPIO 19 -> MISO (optional)
GPIO 22 -> LED (if available)
GPIO 23 -> MOSI / SDA

Step 4: Software Preparation

Arduino IDE

Download and install Arduino IDE if you are not yet do it:

https://www.arduino.cc/en/main/software

ESP8266 Support

Follow the Installation Instructions to add ESP8266 support if you are not yet do it:

https://github.com/esp8266/Arduino

ESP32 Support

Follow the Installation Instructions to add ESP32 support if you are not yet do it:

https://github.com/espressif/arduino-esp32

Arduino_GFX Library

Download latest Arduino_GFX libraries: (press "Clone or Download" -> "Download ZIP")

https://github.com/moononournation/Arduino_GFX

Import libraries in Arduino IDE. (Arduino IDE "Sketch" Menu -> "Include Library" -> "Add .ZIP Library" -> select downloaded ZIP file)

Step 5: Compile & Upload

1. Download the program at GitHub: (press "Clone or Download" -> "Download ZIP") https://github.com/moononournation/COVID-19_WHO_Da...
2. Open COVID-19_WHO_Dashboard.ino with Arduino IDE
3. Fill your WiFi AP settings into SSID_NAME and SSID_PASSWORD
4. If you are not using ILI9341 LCD, comment out line 125 and uncomment the correct LCD class declaration
5. Connect ESP Dev Board to computer
6. Press Upload button to compile and upload the program to the ESP Dev Board

Step 6: Options

• who_adm0_url and who_adm0_new_conf_url is retrieving "China" figure, you can change the value near

"where=ADM0_NAME%3D%27China%27" to your country

• who_adm1_url is retrieving "Hong Kong SAR" figure, you can change the value near "where=ADM1_NAME%3D%27HONG+KONG+SAR%27" to your province, autonomous region, and municipality
• Arduino_GFX library support many size LCDs, the font sizes auto change according to the screen size. I have tested in ST7735 (128 x 160), ILI9341 (240 x 320), ST7796 (320 x 480). You may need make some adjustments for other screen size.

Step 7: Limitation

WHO dashboard figures are according to Coronavirus disease (COVID-2019) situation reports:

https://experience.arcgis.com/experience/685d0ace5...

The figures are update in daily basis and expected have some delay.

Step 8: Happy Quarantine!

This is the time to avoid social contact and stay at home :(

This is also the best time to study on electronics, programming and IoT!
