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 ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

Fig. 1: TM1637 LED module With the TM1637 LED module (Fig. 1) becoming easily available at an affordable price of around ₹90, projects of this kind have become extremely simple to construct. Using an ...

A few months ago I found a led driver module composed of a CN5711 IC, a resistor and a variable resistor. From the CN5711 datasheet: General Description: The CN5711 is a current regulation integrated ...

An Arduino hourglass project is a fun and educational project that involves creating a digital hourglass timer using an Arduino microcontroller and some simple electronic components. The project ...

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 ...

When the receiver receives “1”, the Arduino on the receiver side of the project will turn ON the LED on its side. Similarly, when the data “0” is transmitted by the RF transmitter, the LED on the ...

Each connection to the Arduino I/O drives an LED anode, while the cathodes are joined between the diodes of each plane and go to lines A, B, C, and D, which will be cycled to logic low. So, as far as ...

This module has four dot-matrix LEDs cascaded to form a single LED display to allot more area to the user on the display. Connecting two such modules is easy; just connect output pins of the previous ...
