Netduino Day 1: Basic Input and Output

Posted on by 7 comments

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

Netduino

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.   Netduino SDK

Support us by preordering TrH Meter kit on Tindie

Posted on by 5 comments

We are now accepting pre-orders for the TrH Meter kit through Tindie’s fundraising program, a new feature that they announced a couple days ago. Our target is to receive 20 orders by Dec 31st. So if you pre-order it now, you will get a complete TrH Meter kit for a discounted price of $25 and a thank you note from us for your support in making this funding campaign successful. You will receive a preprogrammed PIC16F688 microcontroller with the kit, which means the kit is ready to go right out of the box. “TrH Meter is a DIY microcontroller-based indoor thermometer

Fancy LED Christmas Tree

Posted on by Leave a comment

Chris from PyroElectro has posted a tutorial on creating an LED Christmas tree controlled entirely by digital logic. His Christmas tree is cone shaped where 64 LEDs spiral around it from top to bottom. Each LED is individually controllable through a 74HC595 shift register output. The clock for shift register is generated using 555 timer IC. The LED Christmas tree can display two types of patters, one is more predictable and another random. Chris is also running a fund raising campaign on Kickstarter to get support for launching a free online Digital Electronics course. For past few years Chris has been

TrH Meter: A DIY indoor thermometer plus hygrometer with adaptive brightness control implemented to 7-segment LED displays

Posted on by 11 comments

This project is about building a microcontroller-based digital room thermometer plus hygrometer that displays temperature and relative humidity on 4 large (1 inch) seven segment LED displays which adjust their brightness level according to the surrounding illumination. It consists of a closed loop system that continuously assesses ambient light condition using an inexpensive light-dependent resistor (LDR) and uses that information to adjust the brightness of the display. An inexpensive DHT11 sensor is used to measure temperature and relative humidity. The microcontroller used in this project is PIC16F688, and it runs at 4 MHz clock generated from its internal source. A
