Cool project to begin with 128x64 OLED, done with a twisted logic to fix the refresh flashing screen.

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

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

A realtime battery indicator for your project without extra components or using any analog I/Os.

Weather forecast clock made from a Nano, a salvaged alarm, a BME280 sensor, a DS1307 RTC, an old cell phone battery, and Nokia 5110 screen.

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

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

Park in your garage with perfect consistency! No more hitting the garage door or workbench!

Arduino tutorial: LED Matrix red 32x8 256 Led driven by MAX7219 (or MAX7221) and Arduino Uno

A digital clock to help small children to differentiate day time and night time through colours.

Arduino stopwatch and lap timer with excelent accuracy and responsiveness!

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

How to drive old binary input HEX LED display with Arduino.

I love swimming, but I tend to lose count of the laps, so I made this lap counter with an Arduino.

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

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

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

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).

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!

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.

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