There are plenty of radios you can buy that pick up MW and SW bands if that’s what you’re into. Or, you can follow [mircemk]’s example, and whip one up yourself instead. The build employs an ESP32 as ...
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 ...
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 ...
The DS3231 RTC module is a real-time clock that uses less power and has highly accurate communication via an I2C interface. Also, the DS3231 real time clock has its temperature-compensated crystal ...
This project aims to display the information entered in a mobile phone on an LED dot-matrix type scrolling display. It is done by interfacing a Bluetooth HC-05 module to an LED dot-matrix display ...
The working of this clock is very simple and similar to other digital clocks. This clock gets the current time and date using the DS3231 RTC module and then this time is displayed on Neo-Pixel LEDs ...
This NeoPixel LED lighting based on WS2811 driver and Arduino digitally produces red, green, and blue (RGB) lights and the combinations. Originally introduced by Adafruit, the LED strips come with ...
Espressif released the [ESP32](https://en.wikipedia.org/wiki/ESP32) last year, a successor to the immensely popular [ESP8266](https://en.wikipedia.org/wiki/ESP8266 ...
