The display shows alternating the current data of different countries of your choice. 3 | 4 | The data is collected by the website www.worldometers.info/coronavirus/ 5 | 6 | ![My image](https://hackster.imgix.net/uploads/attachments/1089824/_tH0IrpXr0o.blob?auto=compress%2Cformat&w=900&h=675&fit=min) 7 | 8 | ## Hardware 9 | 10 | I've used our AZ-Touch kit for ESP32 as hardware plattform. This kit comes with a 2.4 inch tft touchscreen, which will be used for the data output. 11 | 12 | ![My image](https://hackster.imgix.net/uploads/attachments/1089826/mkr_extended_kit_8R81xIIxzy.jpg?auto=compress%2Cformat&w=680&h=510&fit=max) 13 | 14 | You can find all information about the hardware here: 15 | https://www.hwhardsoft.de/english/projects/arduitouch-esp/ 16 | 17 | 18 | ## Libraries 19 | 20 | Install the following libraries through Arduino Library Manager 21 | 22 | Adafruit GFX Library https://github.com/adafruit/Adafruit-GFX-Library/archive/master.zip 23 | 24 | Adafruit ILI9341 Library https://github.com/adafruit/Adafruit_ILI9341 25 | 26 | You can also download the library also directly as ZIP file and uncompress the folder under yourarduinosketchfolder/libraries/ 27 | 28 | After installing the libraries, restart the Arduino IDE. 29 | 30 | ## WiFi settings 31 | 32 | Enter your WiFi SSID & password in the fields in the WiFi section: 33 | 34 | #define WIFI_SSID "xxxxxx" // Enter your SSID here 35 | 36 | #define WIFI_PASS "xxxxx" // Enter your WiFi password here 37 | 38 | 39 | ## Country settings 40 | 41 | You can change/add/delete the countries in the main loop of the program according your interests. 42 | 43 | ![My image](https://hackster.imgix.net/uploads/attachments/1089828/grafik_eRLuAc5tGD.png?auto=compress%2Cformat&w=680&h=510&fit=max) 44 | 45 | 46 | 47 | # License 48 | 49 | This library is free software; you can redistribute it and/or 50 | modify it under the terms of the GNU Lesser General Public 51 | License as published by the Free Software Foundation; either 52 | version 2.1 of the License, or (at your option) any later version. 53 | 54 | This library is distributed in the hope that it will be useful, 55 | but WITHOUT ANY WARRANTY; without even the implied warranty of 56 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
