.NET Gadgeteer Relay Circuit using DigitalOutput Interface

Posted by Michael Dodaro in Embedded Microcontrollers on November 21, 2011

The relay scenario uses a low-voltage logic circuit to control another circuit, usually of higher voltage.  The relay in this example is a 5 volt DC single pole, single throw reed relay. It is used to switch a battery-driven motor on and off.  The switch is controlled by the Gadgeteer.DigitalOutput interface in a .NET Gadgeteer Visual Studio application. The schematic for this […]
