Controlling multiple Arduino pins in VB or C#?
How do I control different pins of an Arduino via VB or C#. Something simple, for instance; if I created 4 buttons. Button 1 would turn ON pin 13, button 2 would turn OFF pin 13. Button 3 would turn ON pin 12 and button 4 would OFF pin 12. I know that it works via a serial port, but I can only control 1 pin. Simple stuff, but I just can't figure it out. PLEASE HELP!!!!
