.NET Gadgeteer Motor Driver with Two Motors and Potentiometer

Posted by Michael Dodaro in Embedded Microcontrollers on March 21, 2012

An earlier post describes how to use a potentiometer with the GHI Electronics Motor Driver L298 module.  This example connects two motors to the motor controller, and the motors run simple mechanical parts, as shown in the following video. There are two buttons that start and stop the separate motors, and a potentiometer controls the speed of […]

.NET Gadgeteer Motor Control with Potentiometer

Posted by Michael Dodaro in Embedded Microcontrollers on March 19, 2012

The GHI Electronics Motor Driver L298 Module provides a method for setting the speed of the two motors it can operate concurrently: MoveMotor(Gadgeteer.Modules.GHIElectronics.MotorControllerL298.Motor _motorSide, int _newSpeed). There is also a method that will ramp up the speed over a time interval: MoveMotorRampNB(Gadgeteer.Modules.GHIElectronics.MotorControllerL298.Motor _motorSide, int _newSpeed, int _rampingDelayMilli). These methods work pretty much as you would expect after […]

Saving Sensor Data as Comma Separated Values (csv) on the SD Card

Posted by Michael Dodaro in Embedded Microcontrollers on March 15, 2012

Data is often persisted in text files as comma separated values. This kind of data can be viewed and analyzed by Microsoft Excel or other spreadsheet software.  Applications based on the .NET Micro Framework and .NET Gadgeteer can easily save data in this format using a module such as the GHI Electronics SD Card module. […]

Posture Regulator using .NET Gadgeteer Accelerometer from Seeed Studio

Posted by Michael Dodaro in Embedded Microcontrollers on March 9, 2012

People who work in technology often spend many hours at the computer, which can make it difficult to maintain good posture.  I’ve been advised by a physical therapist to keep my chest high with my head and neck upright.  The problem is that fatigue tends to make me slouch. Then my neck is out of alignment, […]

New version of Text-To-Speech library

Posted by Marco Minerva in Embedded Microcontrollers on February 26, 2012

Posted by Marco Minerva Some weeks ago I talked about my library for Text-To-Speech with .NET Micro Framework. In the mean time, The Microsoft Translator Service, that I use in my library, has been moved to Azure and has been enhanced with new features. Now it is able to return streams in both WAV and […]

How to Initialize the .NET Gadgeteer WiFi Networking Module

Posted by Michael Dodaro in Embedded Microcontrollers, REST Web Services on February 23, 2012

Initializing the GHI Electronics WiFi RS21 module involves some different issues than initializing the Ethernet_J11D Module.  It took several runs to get my WiFi module working.  I don’t know all the permutations of WiFi networking, so I used a trial-and-error approach. First, I plugged in the WiFi_RS21 module and added start-up code, equivalent to what I have been using with my ethernet module, […]

Text-To-Speech for .NET Micro Framework

Posted by Marco Minerva in Embedded Microcontrollers on January 21, 2012

Posted by Marco Minerva I’m very interested in the possibility of making my applications speak. So, I have realized a library for .NET Micro Framework that uses Microsoft Translator to obtain streams of wave-file speaking text in the desired language. At this moment, there are 44 supported languages, including English, Italian, German, French, Spanish, Japanese […]

Text-To-Speech per .NET Micro Framework (Italiano)

Posted by Marco Minerva in Articoli in Italiano, Embedded Microcontrollers on January 21, 2012

Inviato da Marco Minerva Sono sempre stato appassionato dalla possibilità di far parlare le mie applicazioni.  Ho così realizzato una libreria per .NET Micro Framework che sfrutta Microsoft Translator per ottenere uno stream contenente il parlato del testo che è stato inviato al servizio tramite una chiamata REST. Attualmente, sono supportate ben 44 lingue, tra […]

Modulo Seeed Cellular Radio per .NET Gadgeteer (Italiano)

Posted by Marco Minerva in Articoli in Italiano, Embedded Microcontrollers on January 13, 2012

By Mike Dodaro, translated by Marco Minerva from the original English version Il driver per il modulo Cellular Radio di Seeed Studio è ancora in fase di sviluppo, quindi il codice che lavora con esso non è deve essere considerato definitivo. Detto questo, per usare questo modulo per effettuare chiamate vocali è necessario solo conoscere la sintassi […]

Seeed Cellular Radio Module for .NET Gadgeteer

Posted by Michael Dodaro in Embedded Microcontrollers on January 12, 2012

The drivers for the Cellular Radio module from Seeed Studio are still in development, so any code using this module has to be tentative at this stage. << Note: the new driver  by Eduardo Velloso has now been released: Drivers for the .NET Gadgeteer Cellular Radio Module.>> That said, using the module for voice calling requires only a little information about […]

Controlling the Servo using a Windows Phone application

Posted by Marco Minerva in Embedded Microcontrollers, REST Web Services on January 6, 2012

Posted by Marco Minerva In the post Using a Servo in a .NET Gadgeteer Camera Device we saw how to create a .NET Gadgeteer application that uses a Servo to change the direction of the Camera, takes a photo and uploads it to a Web Service. Now, we’ll realize a Windows Phone application to remotely […]

Seeed Temperature Humidity Sensor with OLED Display

Posted by Michael Dodaro in Embedded Microcontrollers on January 2, 2012

The modules available for .NET Gadgeteer now include some interesting modules by Seeed Studio.  This example uses two of them: Temperature Humidity Sensor OLED Display The application code is very simple, as shown in the following block. Note: Don’t use higher voltage than needed to drive components.  Excess power is dissipated as heat.  After running this example for […]

Using a Servo in a .NET Gadgeteer Camera Device

Posted by Michael Dodaro in Embedded Microcontrollers, REST Web Services on December 22, 2011

The Gadgeteer.Interfaces.PWMOutput interface can support the use of a servo to move mechanical parts of a device as needed by applications. This example uses the Gadgeteer.Interfaces.PWMOutput interface and a servomechanism to turn a camera through an arc of about 140 degrees.  The Pulse Width Modulation (PWM) input for this servo is obtained from a WCF REST Web service running on a remote IIS Server.  The […]

.NET Gadgeteer Gyro Module from Seeed Studio

Posted by Michael Dodaro in Embedded Microcontrollers, REST Web Services on December 15, 2011

Here’s an example that graphically displays data from the Seeed Gyro module for .NET Gadgeteer.  The GHI Electronics Display_T35 module displays the output. Plug the Gyro module into Socket 3.  Connect the display module and a button in the .NET Gadgeteer designer, but do not connect the optional touch-screen cable to Socket 10.  Apparently the touch screen is incompatible with the Seeed Gyro and […]

XML Configuration Files for .NET Micro Framework Applications (English)

Posted by Michael Dodaro in Embedded Microcontrollers on December 14, 2011

By Marco Minerva, translated Mike Dodaro from the original Italian version. All applications require configuration files; we use them to customize behavior and to set parameters unknown at compile time, or those that may change over time (such as the database connection string, the address of the mail server, etc.). .NET supplies the class ConfigurationManager, or WebConfigurationManager for Web applications, to […]

File di configurazione XML per applicazioni .NET Micro Framework (Italiano)

Posted by Marco Minerva in Articoli in Italiano, Embedded Microcontrollers on December 14, 2011

Tutte le applicazioni necessitano di file di configurazione: li utilizziamo per personalizzare il loro comportamento e per impostare parametri non noti in fase di compilazione, o che possono cambiare nel tempo (come la stringa di connessione al database, l’indirizzo del server di posta elettronica, ecc.). .NET fornisce la classe ConfigurationManager (o WebConfigurationManager, nel caso di […]

Sending .NET Gadgeteer Sensor Data to a REST Web Service

Posted by Michael Dodaro in Embedded Microcontrollers, REST Web Services on December 13, 2011

Sending data to a Web service from a device with an embedded microprocessor is a very common and useful scenario.  This example demonstrates the procedures using the .NET Gadgeteer Pulse Oximeter manufactured by Seeed Studio and a REST Web service implemented on the Windows Communication Foundation (WCF) platform. This post has been updated to use HttpHelper.CreateHttpPostRequest. The Seeed Pulse […]
