Implement a Light Sensor Module for .NET Gadgeteer

This example implements a new .NET Gadgeteer module from an Infrared Phototransistor and a 10 kilo ohm pull-up resistor.  It uses the GHI Electronics Extender Module to connect the simple hardware.  The output activates binary logic on a general-purpose digital input/output pin, operating at 3.3 volts.  This case is not difficult to understand.  Many other binary operations can be done […]

.NET Gadgeteer; more Simple Graphics

The Display_T35 module and the DisplayModule.SimpleGraphics object can display various graphics.  This example draws ellipses and sets the colors and sizes of the ellipses according to the voltage a GHI Electonics Potentiometer module.  Just for fun it also matches the color of a GHIElectronics MulticolorLed to that of the ellipse that is drawn on the screen. On each Timer.Tick event the .NET […]

.NET Gadgeteer Display Simple Graphics

This example uses the GHI Electronics Display_T35 module, the Potentiometer, and a Button to demonstrate use of the Display Module Simple Graphics interface.  The application displays circles, or symmetrical ellipses, on an orange background based on the coordinates of a Window.TouchDown event. The size of the circle is determined by the potentiomenter setting. The Display_T35 touch screen displays circles where a […]

Origin of the .NET Gadgeteer Platform

The .NET Gadgeteer platform was created by Steve Hodges and the Sensors and Devices Team at Microsoft Research Cambridge.  Steve was working on SenseCam, a wearable camera that takes photos automatically.  The project took months of research and development, but in the process .NET Gadgeteer was launched.  Devices like SenseCam can now be implemented in hours […]
