COVID-19 Daily Stats on a Nextion HMI using ESP8266

While Covid-19 picks a fight with humanity, keeping busy and your mind clear is important for all of us. In addition to getting out on hikes and biking with the family, what better way to pass the time than to built IoT stuff! Since I had a new 7″ Nextion HMI screen sitting around just waiting for a project, and had some vacation time, I decided to buffer up my skills and get to work. As this project is changing on a regular basis, I will be maintaining the most up-to-date content and code on my blog so please have a look there for the latest. I've posted build into and code.
