The code example simply cycles through the 3 colours

Code

 

#include "mbed.h"
 
DigitalOut redLed(p23);
DigitalOut greenLed(p22);
DigitalOut blueLed(p21);
 
int main()
{
while(1)
{
redLed = 0;
greenLed = 1;
blueLed = 1;
wait(1);
redLed = 1;
greenLed = 0;
blueLed = 1;
wait(1);
redLed = 1;
greenLed = 1;
blueLed = 0;
wait(1);
}
}
