Yes, they have been around forever, but LEDs still make great display devices. Today we will see how to work with both 7-segment and dot matrix LED displays and an Arduino Uno.<\/span><\/p>\n

Introduction<\/span><\/h2>\n

We have worked with several types of displays before, including Liquid Crystal Displays (LCDs) and Organic Light-Emitting Diodes (OLEDs). Each of them has advantages and disadvantages in terms of cost, performance, and ease of use.<\/span><\/p>\n

Today we are getting back to basics and working with LED displays. Despite having been around for over half a century, LED displays are as popular as ever.<\/span><\/p>\n

These make great displays for hobbyist projects, as they are inexpensive and pretty easy to work with. Today, I’ll show you how you can add LED displays to your next Arduino project.<\/span><\/p>\n

LED Displays<\/span><\/h2>\n

Light Emitting Diodes, or LEDs,\u00a0 have been around since 1962, when they were developed by\u00a0 Nick Holonyak at General Electric.<\/span><\/p>\n

During the 1960s LEDs were mostly laboratory curiosities, but in 1969 Hewlett Packard developed an LED equivalent of a Nixie tube, which was a popular display type that used filament with patterns of characters.<\/span><\/p>\n

Cost reductions and manufacturing improvements led to LEDs taking the market by storm in the mid-1970s, bringing consumers a new world of \u201cdigital\u201d appliances like calculators and watches.\u00a0<\/span><\/p>\n

While the original LED displays were red and green, they are now available in a variety of colors. And they come in sizes ranging from almost microscopic to several inches tall.<\/span><\/p>\n

We can break down our LED displays into two basic types:<\/span><\/p>\n
