A clock based on 4 8x8 LED matrix modules with MAX7219, is controlled by an Arduino Pro Mini 3.3v, and includes a DS18B20 digital temperature sensor.

The code is for directly controlling the LED matrix (I had made a 10X8 matrix) through Arduino Uno. Here, I have used multiplexing which makes the task a bit difficult to understand at first. But once ...

The dot matrix clock was built without the use of a regular Arduino board but uses the ATmega168 with Arduino bootloader and assembled on a breadboard. An RTC clock compensated by temperature is used ...

A word clock – a clock that tells time with words, not dials or numbers – is one of those builds that’s on every Arduino neophyte’s ‘To Build’ list. It’s a bit more complex than blinking a LED, but an ...

8×8 LED Matrix modules are now widely available, and fortunately they are easy to use with our favorite Arduino microcontroller. 8×8 LED Matrix module have many applications in real life, such as ...

If you searching for an LED matrix for your next project or to add to an existing application you may be interested to know that the Maker LED Display is now available to purchase from the Crowd ...

Have you ever wanted to build your own IoT-based Weather Monitoring Station? Imagine monitoring real-time temperature, humidity levels, atmospheric pressure, rainfall detection, air quality index (AQI ...

We’re surprised we haven’t seen this kind of clock before, or maybe we have, but forgot about it in the dark filing cabinets of our minds. The above picture of [danjhamer’s] Matrix Clock doesn’t quite ...

What if you could get an instant SMS alert the moment a fire or smoke is detected at home or office? Through this project tutorial, you can build a fire and smoke alarm system using Arduino UNO R4 ...
