One year ago I built a simple Arduino dice with my son. We have learned a lot in the meantime and it's time for an update...

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

I built a simple wood LED clock, using modern electronics and traditional wood and metal working techniques.

A simple to build clock with many features.

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

A very useful project, made to monitor system resources without opening Task Manager.

Small size code and simple hardware. Improved version now available.

Nice looking wooden analog style clock with Arduino Nano and 1mA ammeters.

Arduino stopwatch and lap timer with excelent accuracy and responsiveness!

Simple wall clock using Adafruit 1/4 60 Ring Neopixel

A nice looking clock and thermometer on a large 128x64 LCD screen.

Another clock project with 1, 2" matrix display.

Connect I2C Character LCD Display to Arduino and program it - quick and easy!

A digital clock using minimum components.

A practical device for automatic measuring human height.

In this tutorial, I will be showing you how to get started with the small 0.91 and 0.96 I2C OLED displays using Arduino and NodeMCU.

Display the results from the HC-SR04 ultrasonic sensor on an LCD display using 433MHz transmitter and receiver.

An accurate clock with date displayed on a 16x2 LCD using just the Arduino, the display and few buttons. No RTC module required.

An Arduino code that displays on a small 0.98" OLED SSD1306 Date/Time and also calculates and displays Salat Time for a given town

FFT spectrum analyzer is a test equipment that uses Fourier analysis and digital signal processing techniques to provide spectrum analysis.

Modified exisiting project to include some sensors and extra buttons. Can use ESP01 to set time via NTP.

A cool digital clock which sports the 7 segment display. With its bright red display will make sure you like to keep an eye at the time.

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

Driving a Single Digit 7 Segment LED Display requires 8 of an Arduino's 20 or so I/O pins. Using a 74HC595 shift register only requires 3.
