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 is an amazing digital clock with automatic cancellation of the mirroring effect! Just move it in front of a mirror and be amazed!
Digital and binary Clock using Arduino, RTC, two LED matrix, operating in 4 different modes (AM-PM / 24 HS / 02 types of fonts).
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.
Arduino stopwatch and lap timer with excelent accuracy and responsiveness!
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.
This video tutorial shows you how to program line by line.
