A large, WiFi-connected seven-segment clock built from addressable LED strips, driven by an ESP32. Each digit is drawn on a NeoPixel (WS2812) strip, the time is synchronised over the internet, and the ...

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...

There’s a long history of devices originally used for communication being made into computers, with relay switching circuits, vacuum tubes, and transistors being some well-known examples. In a smaller ...

A 7-segment display is commonly used in electronic display devices for decimal numbers from 0 to 9 and, in some cases, basic characters. The use of light-emitting diodes (LEDs) in seven-segment ...

The exact time and date are obtained from the Network Time Protocol via Wi-Fi. For a smaller display, about 0.8-inch schematic diagram is very simple. Problems are with large segments, containing more ...

This project is also available at Max Imagination’s Workshop. Welcome, fellow makers! Today, we're diving into the world of productivity and time management with a hands-on project – the Arduino ...
