This clock gets the current time and date using the DS3231 RTC module and then this time is displayed on Neo-Pixel LEDs using Arduino Pro Mini. The working of this clock is very simple and similar to other digital clocks. Components to build your own Rainbow Clock About the clock I made, it's a very simple clock that shows time and room temperature and the main feature of this clock is that the color of the digits changes every minute. So, here I am going to use Neo-Pixel LEDs with Arduino pro mini and RTC module. While searching for the clock model, I got thousands of designs but most of them were using seven-segment displays and I wanted to build a unique and colorful clock without using Seven segment display. So, I decided to make one Arduino digital clock for my room. Mehrdad Majzoobi has updated the project titled Ubo project: building for builders.I know making a clock sounds a little irrelevant, especially nowadays because we all have smartphones and no one is going to use or look into the clock for time, but it is good when you are doing some work or during the workout.Paul Ellison liked When a crystal radio meets a regen receiver.Paul Ellison liked Furby Borges reborned.Peter Sinclair has updated details to Badminton ACE Shuttle Launcher.Bindhammer has updated details to Pill dispenser robot.

Occasionally, has the clock display a quick effect, such as a Pac-man or a radar scan animation.Īll the files are up on the Github page, including the Blender models for the case, available to build your own and a simple search for “241 LED ring” turns up the LED hardware used. An ESP8266 runs the code and controls the LEDs getting the time from an NTP server. wanted the second hand to rotate smoothly, so it is updated using the milliseconds as an offset to the second. ![]() Each hand of the clock is a different color and is antialiased to give a smoother look, since the LEDs don’t line up. The rings aren’t wired together, and it seems like these are designed to be separated, but it’s pretty easy to wire them together in order to have a circle of individually accessible RGB LEDs. ![]() found a circle of LED rings online and with made an LED version of an analog clock. You can build anything from a seven-segment display to a binary clock or something even more fancy. Building a clock of some sorts seems to be a time honored tradition for hackers and LED clocks seem one of the most popular.
