A simple to build clock with many features.

Small size code and simple hardware.

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

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

Simple wall clock using Adafruit 1/4 60 Ring Neopixel

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

Arduino stopwatch and lap timer with excelent accuracy and responsiveness!

Another clock project with 1, 2" matrix display.

An Arduino based word clock that tells the day of the week, the month, day and year and the time to the minute in words.

My first Arduino build. RTC displayed on I2C LCD and Legos!

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

Designed for crew rowing, this speedcoach is designed to track split times and total meters traveled.

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

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...

Another one of the series of unusual clocks I made.

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

A digital clock using minimum components.

2 x 16-band audio spectrum analyzer with Arduino Nano and 2 x 16 chars LCD display. This project is based on Shajeeb's project.

Small board - great value (for how a little Arduino Nano is improving our Toastmasters meetings).

Make your projects colorful.

A word clock using an OLED display.

A simple to build LED matrix flip clock.

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

Driving a Single Digit 7 Segment LED Display requires 8 of an Arduino's 20 or so I/O pins. Using a 74HC595 shift register only requires 3.
