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

Make your projects colorful.

A word clock using an OLED display.

Digital and binary Clock using Arduino, RTC, two LED matrix, operating in 4 different modes (AM-PM / 24 HS / 02 types of fonts).

Small size code and simple hardware.

This is a clock with its digits out of order. Within the apparent chaos is a beautiful order! Very easy to use including an alarm clock!

This video tutorial shows you how to program line by line.

Photo frame that counts the number of days spent together.

A clock, controlled by a RTC module, that you can see on a 4-digit display.

A simple to build LED matrix flip clock.

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

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

Another clock project with 1, 2" matrix display.

Want to display text? Here is your component!

This is a random number generator using 8x8 LED matrix and Arduino. It is adjustable from 1 to 60 and includes a timer play mode.

Digital clock with Arduino using Shift Register (74HC595), real time clock, temperature and humidity sensor and 7 Segments display.

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

This is an amazing digital clock with automatic cancellation of the mirroring effect! Just move it in front of a mirror and be amazed!

This is the Digital & Binary Clock in 8 Digits x 7 Segments LED display with Arduino, MAX72xx and DS1307 RTC.

This digital clock driven by Arduino is a fun emulator of 4-stroke engine where the digits of hours & minutes represent the pistons moving.

Arduino stopwatch and lap timer with excelent accuracy and responsiveness!

This clock can be rotated in any position keeping the digits readable even upside down or in a mirrored image!

This project is about an Arduino running a digital clock, a stopwatch, and a timer simultaneously!

This clock uses the first 192 digits of Pi number to display the time in a 32 x 8 LED matrix in an original way.
