SharePort also allows (trusted) friends on my network to fire off files to a printer connected to my router via USB. The beauty of SharePort is that it knows when a print job is finished and automatically disconnects users from the USB-attached printer.
The pins on the Arduino can be configured as either inputs or outputs. This document explains the functioning of the pins in those modes. While the title of this document refers to digital pins, it is important to note that vast majority of Arduino (Atmega) analog pins, may be configured, and used, in exactly the same manner as digital pins.
The following schematic controls red from arduino pin 6, green from arduino pin 10 and blue from arduino pin 11. Go ahead and hook this circuit up. Arduino circuit to control the color of an RGB LED. Now lets play around with a program that will independently turn on the different colors.s you can see in the schematic, all three of the LEDâs share a common ground pin. You can easily see that pin should be connected to your circuit ground. Now, think about how you would connect the control pins. To control a normal LED, you needed to connect to one arduino output pin.
