The circuit is driven by a MAX7219 IC that is being controlled through an Arduino microcontroller board, to create an 8X8 LED matrix. The connection of the LED matrix and the IC was done on a ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

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 ...

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 ...

Okay, I knew this would happen - one Arduino clock leads to another. Take a look at a clock that tells the time in terms of the first 192 digits of Pi, via a 32 x 8 LED matrix... Dubbed the Pi Day ...

Makers, developers and electronic enthusiasts may be interested in a new Arduino programmable Internet connectable LED matrix display launched via the Crowd Supply website this week, which is now ...

Most of us have an 8x8 LED matrix from one of our Arduino kits. What can we do with them? This module investigates how to use these interesting devices. Along the way, we describe a fun electronics ...

I like this. Following on from the creative use of LEDs with the Periodic Table, check out this smart shelving system, similarly driven by an Arduino and using LEDs, that serves as a clock. Not a ...

A digital camera has an array of sensors that captures light reflected or transmitted onto it. This build is something closer to a reverse camera – a single sensor that makes images on a matrix of ...
