That is not the way to simply turn on the laser LED. When you set motor C
to forward the LED will commence sending VLL motor forward commands out the
LED which, of course, will result in a flickering LED.
The Scout worked the same way - the LED would flicker because it was sending
a pattern of flashing lights that a VLL receiver would interpret as a motor
command.
With NQC just use:
SetLight(LIGHT_ON);
or
LED(LED_MODE_ON);
Here's a modified version of 5_light.nqc. Using two light pipes that are
held close together at the far end (and pointed directly at the ground about
a 1/4 inch above the ground) I am able to detect the presence of a dark
stripe on a light surface. I used a technic cam to hold the ends of the
light pipes with a simple frame extending from the rear of the spybot to
hold everything in the correct position. Can someone work up a "good"
structure for this? Mine is definitely just a quick and dirty hack.
// 5_spy_light.nqc
#define THRESHOLD 40
task main()
{
SetLight(LIGHT_ON);
SetSensorMode(SENSOR_2, SENSOR_MODE_PERCENT);
OnFwd(OUT_A+OUT_B);
while (true)
{
if (SENSOR_2 > THRESHOLD)
{
OnRev(OUT_B);
Wait(10);
until (SENSOR_2 <= THRESHOLD);
OnFwd(OUT_A+OUT_B);
}
}
}
