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 ...

This code uses drives a 4 digit alphanumeric LED display: LINK using a shift register: [LINK] (https://www.sparkfun.com/products/733)... Please see the file schematic ...

In my hand is a 4-Digit 7-Segment display module. The heart of this module is an inexpensive Serial LED Driver from Titan Micro Electronics called the TM1637. In this tutorial, I am going to show you ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

Charlieplexing is a technique of controlling many LEDs using a few I/O pins. Charlieplexing is same as multiplexing, but it uses the tri-state logic (high, low input) to reduce the number of pins ...
