While debouncing needs improvement, it's a good start to understand interrupts!

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

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

A simple clock using LED matrix and RTC to display the time, date and temperature.

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

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

Arduino stopwatch and lap timer with excelent accuracy and responsiveness!

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!

Text Clock with Arduino that can display the time in two languages: English or Portuguese.

Would you like to train your reaction time in milliseconds? Now you can with a timer inspired by the F1 race start lights.

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.

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

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

This LED Display Module can works with two-color LED matrix in two sizes (large and small), as well a 7 segments x 4 digits.

This is an uncommon digital clock that can run in three different modes: mode digital and two different modes of binary clock.

The simplest Arduino LCD clock ever designed. Only needs an Arduino UNO, a 1602 LCD, and two buttons. No resistors, no potentiometer.

This is how to make your own LCD timer, just with an Arduino, a LCD screen and some hook-up wires.

A unique TFT shield expanding the capabilities of an Arduino Uno.

In this project I'll show you a simple way to control a 7 Segment Display with a keypad!

An alarm clock showing the Jewish (Hebrew) date, the Gregorian date, current time, time of nightfall, sunrise, etc

A 20x4 RGB LCD clock that can display over 500 poems using Arduino and an SD card reader.

48x8 Programmable Scrolling LED Matrix using Arduino and Shift Registers.

Here, you will learn how to use TFT LCDs by Arduino. From basic commands to professional designs and technics are all explained here.

Using two Seven-Segment Displays (SSD) simultaneously on an Arduino Uno Board to display numbers from 00 to 99, without charlieplexing.
