Arduino library for 7-segment LCDs based on the HT1621 driver, with support for 4-digit displays and various low power modes. Often marked as PDC-6X1 (6-digits) or LCM0220 (4-digits). Based on the ...

For the right pins see the following schema: This pins layout will fit the LCD above but it can be easily changed in the code. To connect the digit pins you may want to use a resistor (e.g. 1k). It ...

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 ...

Connecting Seven Segment Display with Arduino Now let’s see how we can drive a seven-segment display with an Arduino. For that let’s start by placing the display module on a breadboard with the ...

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 ...

Sometimes you need to display a number nice and large, making it easily readable at a good distance. [Lewis] has just the thing for that: a big expandable 7-segment display. The build is modular, a… ...
