Netduino Day 3 – Multiplexed Seven-Segment LED displays

Posted on January 17, 2013 by ANir 6 comments

A visual output always adds value to any project. In this third day tutorial, we are going to display some numeric, alphabetic as well as two symbolic characters on a 4-digit seven segment LED module. The way we are interfacing the seven segments LEDs is known as multiplexing, which allows to save some I/O pins of Netduino as compared to driving them individually. The seven segment LEDs are resource and power hungry, but we are going to do this experiment just to get our feet wet in the microcontroller or embedded world and to understand the basics of a seven

Netduino Day 2: Interfacing a Character LCD

Posted on December 28, 2012 by ANir 6 comments

Liquid Crystal Displays (LCD) are a great choice of output device for displaying alphanumeric characters in real time. They are also very useful if your project requires an interactive user interface for data input. Besides, they are inexpensive, consume less power than LED displays, and give a more professional look to your project. Today we will explore how to interface an HD44780 based character LCD to Netduino to display alphanumeric characters. For technical details of the HD44780 driver, please read its datasheet as well as its interfacing example with chipKit.

Netduino Day 1: Basic Input and Output

We will start our Netduino tutorial series with a very basic project of flashing an LED. The objective of this project is to explore basics of Netduino I/O pins as well as to make sure that everything is setup correctly, including software installation and hardware setup. In this project, we will use an Analog pin to read a potentiometer’s analog output, and a digital pin to flash an LED. The frequency of LED blinking is varied based on the potentiometer output. It will blink at an interval of 10 milliseconds to 1000 milliseconds based on the wiper position of the potentiometer.

Getting Ready for Netduino / Netduino Plus Tutorials

There are a few things that need to be done besides simply connecting the Netduino to the computer. I will be using Netduino Plus for the tutorials however Netduino and Netduino Plus are more or less the same for our tutorials. Let’s first list all the necessary tidbits: Microsoft Visual Studio (C# or VB) Express 2010 http://www.microsoft.com/visualstudio/eng/products/visual-studio-express-products Using this software we will be writing our codes in VB.NET or C#.NET. .NET Micro Framework SDK v4.1 http://www.netduino.com/downloads/MicroFrameworkSDK.msi Without this, we will not be able to write code that Netduino (or any Micro Framework supported hardware) will understand.
