LCD Character Display Modules & Accessories STN- Y/G Transfl 84.0 x 44.0

Welcome to another episode of the 8-Bit Guy. So, in this episode I want to show you how character LCDs work. Now, these things have been around since at least the 1980s. You can find them in all kinds of electronics like old computers, music keyboards, synthesizers, calculators, early mobile phones, laser printers, and are still widely used today on servers, and for hobby projects with microcontrollers. In fact, they are ridiculously cheap now and you can find them all over ebay for just a few Dollars in just about every shape, size, and color you could want. They come in as small as 8 by 1 characters. Some other common sizes are 8 by 2, 16 by 2, and 20 by 4. These screens should all have either 14 ot 16 pins on them. They can be arranged in different ways, but they should be labelled 1 through 14. I’m going to start by showing you what each of the 14 pins do. The first pin is ground. T
