Last time, I used an Arduino to build a small clock that retrieves the time via Wi-Fi.Click here for the previous article: I ...

Most hobby weather stations die the moment the Wi-Fi drops. The phone app goes blank, the cloud dashboard freezes, and the data you were collecting is gone. I wanted the opposite: a station I can set ...

Back in July, I attended Open Sauce for the first time. It was an awesome event and I also brought along a custom badge I designed! To my surprise, upon entry to the event you also get a free badge ...

Infrared (IR) communication technologies are probably one of the most influential, yet also one of the least flashiest. The fact that IR communication tends to be highly directional and often limited ...

Digital clocks are one of the most popular Arduino projects, and most of them use traditional seven-segment displays to show the time. While these displays are simple and reliable, they usually have ...

M5Stack has just introduced the ToughC5, a rugged, weatherproof outdoor IoT controller built around the ESP32-C5. The device features a bright 2.0-inch capacitive touch IPS display and RS485 ...

Broadcast radio isn’t as popular as it once was, its popularity suffering in turn due to technologies like MP3 players and music streaming services. If you don’t fancy either of those, you might like ...

The device features a bright 2.0-inch capacitive touch IPS display and RS485 connectivity. The ToughC5 is an upgrade to the ESP32-base3d M5Stack TOUGH introduced in 2021, with the upgraded model ...
