Make beautiful music with Adafruit, SparkFun, Arduino and ProtoStax! Create an RGB matrix audio visualizer with Arduino.

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 video tutorial shows you how to program line by line.

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 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.

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.
