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 and binary Clock using Arduino, RTC, two LED matrix, operating in 4 different modes (AM-PM / 24 HS / 02 types of fonts).
Make beautiful music with Adafruit, SparkFun, Arduino and ProtoStax! Create an RGB matrix audio visualizer with Arduino.

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 an uncommon digital clock that can run in three different modes: mode digital and two different modes of binary clock.
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.
This digital clock speaks 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 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.
Text Clock with Arduino that can display the time in two languages: English or Portuguese.
