Here is a 3D light show that will astound you with its combinations. Inexpensive and easy to make thanks to an Arduino controller, the design enables you to play with the existing effects and, most ...

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 ...

The purpose of a clock is to show the time, obviously. But if you’ve followed Hackaday for some time, you’ll know there are about a million different ways of achieving this. [illusionmanager] added ...

Perhaps one of the most common modules in an Arduino starter kit, the RGB LED lets you create all sorts of colors with just four pins from the Arduino. This tutorial demonstrates two ways to use this ...

Arduino uno “smartwatch” built upon a breadboard. With modules to tell the current time, sense temperature and humidity, and show the data in a 7-segment display or on an LCD display.
