This is just a fun Arduino project that uses leds connected in circle as a ring to produce a rotation effect. You can adjust the spinning speed with a potentiometer and you can also set a minimum and ...

Digital-Potentiometer-and-LED-Ring-Driven-by-Arduino This project aims to experiment with the digital control of a digital potentiometer type M62429 and an RGB LED ring. This is done by an Arduino ...

An Arduino-based analog clock using an WS2812B addressable RGB LED ring as a display. This sketch requires the FastLED library, the Wire library (built-in), the EEPROM library (built-in), and the ...

Pulse-width modulation (PWM) Pulse width modulation (PWM) is a powerful technique for controlling analog circuits with a microprocessor’s digital outputs. Pulse-width modulation,as it applies to LED ...

Learn how a pulse sensor works and how to interface it with Arduino to measure heartbeat accurately in this comprehensive guide.

There are LED clocks, and then there are LED clocks that can blind you from 30 paces. [Stiggalicious’s] LED ring clock is of the latter variety. 200 WS2812B/Neopixel RGB LEDs drive the ring c… ...

So he decided to 3D print a ring and embed a slowly pulsing LED in it. He does mention that this ring is a temporary solution, so perhaps his soon-to-be-Mrs will receive something sparkly and ...
