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

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

Just part of a big project while I'm doing testing on DS3231 RTC module with LCD keypad shield. I think this can be shared.

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.

An open source VR headset that you can build yourself for $100.

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

Arduino stopwatch and lap timer with excelent accuracy and responsiveness!

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

Control the LCD contrast and background LED with analogWrite!

It counts the amounts of 1Rs, 5Rs and 10Rs coins as well as the total amount of coins.

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

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 speaks the time in two languages (English or Portuguese).

This project is one of a series of projects that is aims to create tools that helps in so many ways.

Globe Trotter is a fun and tangible picture viewer.

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

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

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.

This project explains how to use a dual Clock using DS3231 on 1.8" ST7735 Display

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

An Arduino UNO large clock on a 16x2 LCD display shield with the ability to change hours and minutes.

This project introduces to you a tiny calendar using a LED Matrix and includes many features like the Moon phase!
