[OmrFV97]

Hi

I need to control 3 Led with Labview over Arduino.But i cannot figure out i made 1 Led control how can i add 2 more Led on this Arduino code and Labview vi.

Thank you

My Arduino Code.

int led;
void setup() {
Serial.begin(9600);
pinMode(13, OUTPUT);
}
void loop() {
if(Serial.available ()> 0)
{
led = Serial.read ();
if (led == '1')
{
digitalWrite (13,1);
}
else if (led == '0')
{
digitalWrite (13,0);
}
}
}

Hi OmrFV,

you need to define more/other commands to send from LabVIEW to your Arduino.

You might:

• use an integer number and encode the LED states in the bits of that integer, like 0=all off, 5=LED1&LED3 on…
• use a string of 3 chars to control 3 LED, like "000" all off, "101" LED1&LED3 on…
• use separate commands for each LED, like "LED1=0;LED2=1;LED3=1"…
• any other idea you get…
