Cheap and easy to build using VirtualPanel

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

A simple to build clock with many features.

This project is similar to my previous one but uses the FHT library which turns out to be at least 4 times faster than the FFT.

Another clock project with 1, 2" matrix display.

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...

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

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

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

A practical device for automatic measuring human height.

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

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.

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

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 to build LED matrix flip clock.

Complete tutorial on how to control 8x8 Matrix when you do not want to use driver chips like MAX2719 and corresponding Libraries.

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

A useful device that serves for a short-term local and three-day weather forecast.

Simple wall clock using Adafruit 1/4 60 Ring Neopixel

How to build an Arduino-based big LCD clock with two alarms and temperature monitor controlled by IR TV remote.

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

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

The construction is completely simplified, and the clock face is printed with a printer on a plain sheet of paper.

Great instrument for short time local weather forecasting. Uses only Arduino, BMP180 and 9g servo.
