A simple setup using an Arduino Nano and an LCD Keypad Shield to set the date, time and alarms for a DS3231 Real Time Clock (RTC).

Arduino Nano 32x8 LED matrix displaying date, time, temperature and humidity with a motion sensor.

A very useful project, made to monitor system resources without opening Task Manager.

Small size code and simple hardware.

A digital clock using minimum components.

Complete Digital Clock including many features: Alarm, Temperature, Humidy, Dew Point, RTC and PIR (Presence Infrared Sensor).

A simple to build clock with many features.

Arduino stopwatch and lap timer with excelent accuracy and responsiveness!

Another clock project with 1, 2" matrix display.

I built a simple wood LED clock, using modern electronics and traditional wood and metal working techniques.

One year ago I built a simple Arduino dice with my son. We have learned a lot in the meantime and it's time for an update...

A cool digital clock which sports the 7 segment display. With its bright red display will make sure you like to keep an eye at the time.

A nice looking clock and thermometer on a large 128x64 LCD screen.

Nice looking wooden analog style clock with Arduino Nano and 1mA ammeters.

Another one of the series of unusual clocks I made.

A practical device for automatic measuring human height.

This project is similar to my previous one but uses the FHT library which turns out to be at least 4 times faster than the FFT.

An Arduino code that displays on a small 0.98" OLED SSD1306 Date/Time and also calculates and displays Salat Time for a given town

Modified exisiting project to include some sensors and extra buttons. Can use ESP01 to set time via NTP.

Project is showing simple stopwatch with start, stop and restart. It's a great project for learning how to use LCD with Arduino UNO or NANO.

Connect I2C Character LCD Display to Arduino and program it - quick and easy!

A simple to build LED matrix flip clock.

An analog/digital clock using Arduino Nano, DS1307 & Nokia 5110.

A simple countdown timer that makes you wash your hands for at least 20 seconds.
