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

A simple to build clock with many features.

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

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

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.

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.

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

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

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

Another clock project with 1, 2" matrix display.

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

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

Arduino stopwatch and lap timer with excelent accuracy and responsiveness!

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

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...

A digital clock using minimum components.

Project is showing simple stopwatch with start, stop and restart. It's a great project for learning how to use LCD with Arduino UNO or NANO.

A simple countdown timer that makes you wash your hands for at least 20 seconds.

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.

Make your projects colorful.

Simple wall clock using Adafruit 1/4 60 Ring Neopixel
