Digital 60 led clock analog style with RTC DS3231

Decimal/binary clock that also displays sun set or sun rise and other functions.

Clock without using RTC in Arduino with Temperature and humidity indicator

Create an OLED screen that shows the date, time in digital and analog format, temperature and humidity.

This alarm clock and timer work without the help of a computer. All the settings can be done on the clock itself and stored in the EEPROM.

Making a big digital wall clock using Arduino Mega 2560, 5054 LED strip, DS3231 RTC, IRFZ44N MOSFET transistor, and aluminum profile.

Flip Dot Clock is a clock using Flip Dot Display. It's a matrix of colorful dots flipped by electromagnet, not LED.

Using 128×64 monochrome display with ST7920, I made an adjusting RTC clock based on an Arduino board.

Another type of clock, which needs a bit of thinking, before you can read it...

This is an alarm for your house that rings when a movement is detected, like when the door is open or when a body walks in front of it.

Most hygrometer sensors are known for quickly corroding. This project takes advantage of a RTC to trigger the watering for a herbal garden.

This project will show you how to make a simple Clock using a RTC Clock and a LCD.

This project demonstrates the use of electronics and embedded system with clock.

Never forget to turn ON/OFF your aquarium lights.

An interesting representation of time using three dominos.

A simple Arduino-based temperature data logger

Arduino-controlled Christmas Tree lit by 150 digital RGB LED pixels. The RTC chip switches on and off the tree at the planned hours!

A compact air quality, temperature and humidity monitor enclosed in a small wooden chest, with a four-row LCD display.

This project will show you how to make a probe using a datalogging Arduino shield, some sensors and an RTC.

We're proud to present our new project, “EPOXY RESIN LED CLOCK."

Ever wanted to make a project that activated on a schedule? Using a Real Time Clock (RTC) is a great way to do it!
