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.

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

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

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

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

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.

A simple Arduino-based temperature data logger

Never forget to turn ON/OFF your aquarium lights.

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

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

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!

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

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

THGadget is a temperature, humidity and date/time Arduino Mega 2560-based device. The sensors: DHT11 and RTC HT1380.

Fast function getDS1307timeStamp().

For Arduino Yùn, adds new REST commands, enabling tunnelling for I2C messages.
