Liquid Crystal Displays(LCDs ) are a very popular output device for displaying graphical and alphanumeric data in microcontroller based systems. They can also provide an interactive input interface to the users. The most common type of LCD controller used by hobbyists is the Hitachi 44780, which provides a relatively simple interface between a processor and […]
Interface with a microcontroller from a web browser, using HTTPS and a simple Python server. Story I love microcontrollers. I also love controlling hardware remotely, say, from another room of my house. The idea of being able to do this through a browser, like from my laptop or phone, rather than from an ssh console.

Alphanumeric LCD displays have become very popular for microcontroller applications because they can add a lot to a project in a variety of different ways. A text message giving the user instructions as well as feedback can make the application seem much more “professional” and easy to use. I like to use LCD’s to help
In this tutorial we will see How to interface a 16×2 character LCD Module with PIC 16F877A Microcontroller using CCS C Compiler. 16×2 character LCD is a very commonly used LCD module in electronic projects and products. 16×2 means it can display 2 rows of 16 characters. It is a very basic and low cost
