A general purpose USB Relay controller for connection to a PC's USB port using VCP (Virtual COM port). Control devices using your PC. USB Relay controller allows a PC to control a single external device using simple RS232 commands. Relay is fully powered from the USB bus.
The plugin allows to control this device.
This example shows how to control an arduino board connected by usb interface in order to switch on/off a led. The code is very simple but it's a base from which to create more complex plugin using serial protocol. It uses our Serial framework (based on RXTX project) so read this tutorial for more info.
