Advice on very simple project for newbie please.

PaulS:
If what you meant was how to develop a program in VB that talks to the Arduino, that is quite a different story.

Take a peak at all the ways that a PC, phone, etc. can talk to the Arduino.

Hi.

That looks useful thanks.

I'm wondering if it's too complicated for what I'm after though.
I have a red led on pin 11 and a green led on pin 12.
My .net program just needs to send 4 commands:

  • both off
  • both flashing
  • red only on
  • green only on
    Is it possible to find out the code the arduino needs to do this and simply send it out to the serial port?
