Control an MAX7219 with an HC-06 Bluetooth module and your mobile phone.

A realtime battery indicator for your project without extra components or using any analog I/Os.

An Arduino analog clock refreshed by GPS on TFT display - Steampunk GPS Clock.

Gixie Clock is a modern device that reproduces the retro beauty of Nixie tube displays.

This project is one of a series of projects that is aims to create tools that helps in so many ways.

It shows the current temperature on an 8*8 dot matrix display using DHT11 temperature sensor.

This digital clock driven by Arduino is a fun emulator of 4-stroke engine where the digits of hours & minutes represent the pistons moving.

A very easy Genuino UNO project with LCD and DHT11 temp. and humidity sensor. The LCD shows the temp., humidity and other infos.

Monitor Oil Temp and Pressure, Water Temp, Voltage, Fuel level. Display on Nextion display or Nokia LCD

In 1884 Nipkow invented a method to capture and view a moving image. This project uses the same disk to generate a moving digital image.

This alarm clock and timer work without the help of a computer. All the settings can be done on the clock itself and stored in the EEPROM.

Arduino version of the early mechanical television, invented by Nipkow more than 100 years ago.

This is how to make your own LCD timer, just with an Arduino, a LCD screen and some hook-up wires.

A weather clock with Arduino, RTC, DHT22 and BMP180.

This project is about a stopwatch including the feature of lap time counter and controlled by Arduino (Nano or Uno).

Using a smart GPU2, a smart SHIELD and Arduino we created a simple touchscreen oscilloscope!

This project introduces to you a tiny calendar using a LED Matrix and includes many features like the Moon phase!

Temperature, humidity and barometric pressure showing a comparison to a previous point in time and graphing the trend.

How to make an easy and adaptable countdown.

An Arduino planetarium on 2,8" TFT display for your gps location. no internet connection!!! All the planetdata pre-stored on the Arduino.

A simple but beautifully accurate PWM frequency meter.

This is the Digital & Binary Clock in 8 Digits x 7 Segments LED display with Arduino, MAX72xx and DS1307 RTC.

Watching primes born was never more exciting, or slow.

Control the LCD contrast and background LED with analogWrite!
