When using Firefox, the browser is made up of 3 columns, which means there is less space on the page than the browser window. Such a thing usually does not happen in new modern designs. We can make changes to the interface of the browser by creating its own css fill in Firefox. You need to create a folder and a file to make adjustments on your computer.
Public use on open networks is sometimes only open to some ports with all ports disabled. In such cases, we prefer 443 port on our VPN servers. It is not possible to provide both web and VPN services from a server using the same port under normal conditions. A port at an IP address can only use one program.
Sometimes we need high speeds when we uploading our projects from the server or downloading from the server. My service provider lowered the upload speed from 4 megabits to 2 megabits, this is a very bad situation for me.
I bought two nodemcu from aliexpress. It is too cheap but wifi range maximum 20 meters. Okay lets test wifi range. You need 2 Nodemcu , 4 double A batteries and hand skills. One of client other one is hotspot.
Today we make a simple voltage meter with Arduino. When I testing the ESP WiFi range, I found that the wifi range too low. I need a multimeter but not found around me. I use arduino as multimeter. Open Arduino IDE Software. Write code below on your project.
