XBee Radios in .NET Gadgeteer Devices

XBee radios are inexpensive and they can be embedded in all kinds of devices.  XBees can be networked so that a failure of one radio does not impar communication between and among others in the network.  Their range exceeds that of Bluetooth connections.  The article Zigbee Networking with XBee Series 2 and Seeed’s Products provides a quick overview of XBee […]

Controlling a Gadgeteer device using Bluetooth Module and 32feet.NET library

Posted by Marco Minerva In this post, I’ll show how to send messages to a GHI Bluetooth module from a PC application using the 32feet .NET library. First of all, let’s create the Gadgeteer application. Connect an USB ClientDP and an OLED Display to a FEZ Spider Mainboard, as in the following screenshot. .NET Gadgeteer […]

Mind Control of .NET Gadgeteer Device via Neurosky EEG Sensor

This experiment leaves much to the imagination, but it does demonstrate how wave forms of the human brain can determine events on a device with an embedded microcontroller.  This code scenario is submitted for use in the Open Health and Fitness Data Aggregator project headed by Ira Laefsky. The Neurosky Mind Wave sensor is an economical electroencephalograph designed for extensibility with other applications.  For less […]

.NET Gadgeteer Bluetooth Control of Motor Driver

A previous example .NET Gadgeteer Motor Driver with Two Motors and Potentiometer demonstrated the GHI Electronics Motor Driver L298 module.  This post uses a similar code scenario, but in this case we control the motors from a serial console that sends messages to a GHI Bluetooth module on the device.  This example also demonstrates how to reverse direction of the motors. The Bluetooth […]

.NET Gadgeteer Motor Driver con due motori e un potenziometro (Italiano)

By Mike Dodaro, translated by Marco Minerva from the original English version In un post precedente ho descritto come usare un potenziometro con il modulo GHI Electronics Motor Driver L298 module. Questo esempio collega due motori al driver, i quali fanno muovere delle semplici parti meccaniche, come mostrato nel video seguente. Ci sono due bottoni che avviano e fermano i […]

Controllare un motore con .NET Gadgeteer e un potenziometro (Italiano)

By Mike Dodaro, translated by Marco Minerva from the original English version Il modulo GHI Electronics Motor Driver L298 fornisce un metodo per impostare la velocità di due motori che possono funzionare contemporaneamente: MoveMotor(Gadgeteer.Modules.GHIElectronics.MotorControllerL298.Motor _motorSide, int _newSpeed). C’è anche un metodo per aumentare la velocità in un certo intervallo di tempo: MoveMotorRampNB(Gadgeteer.Modules.GHIElectronics.MotorControllerL298.Motor _motorSide, int _newSpeed, int _rampingDelayMilli). Questi […]

Eduardo Velloso completes Beta Driver for .NET Gadgeteer Bluetooth Module

Since the Bluetooth Module was released by GHI Electronics there have been numerous users who have found it difficult.  The starter driver was rudimentary.  Windows and other devices could not discover it or connect to it unless a developer who knew a lot about Bluetooth protocols implemented the Gadgeteer device.  The references available were manufacturer specifications. GHI Electronics invited the community to […]
