These days, connecting your microcontroller project to a WiFi network is pretty easy — you connect up an ESP8266 to your microcontroller project and pretend it’s a WiFi modem, using these ...

The ESP8266 is the answer to “I want something with Wifi.” Surprisingly, there are a number of engineers and hobbyists who have not heard of this chip or have heard of it but don’t really understand ...

This project uses an WEMOS D1 Mini ESP8266 module and an Arduino sketch to connect to a NTP (Network Time Protocol) server to automatically retrieve and display the local time on a inexpensive analog ...

Electronics is an expensive hobby. You often need to buy expensive hardware to complete a small hobby project. Fortunately, searching will give you a long list of cheap “retired” parts. If you’re sure ...
