Set blue led intensity

To set the intensity of :ref:`blue_leds`:

// Set led L0 in left ear to intensity 1.0
nao_lola_command_msgs::msg::LeftEarLeds left_ear_leds;
left_ear_leds.intensities[nao_lola_command_msgs::msg::LeftEarLeds::L0] = 1.0;

Set color of RGB led

// Set red led in L0 of left eye to intensity 1.0
nao_lola_command_msgs::msg::LeftEyeLeds eye_leds;
eye_leds.colors[nao_lola_command_msgs::msg::LeftEyeLeds::L0].r = 1.0;

Set color across all leds

To populate all LEDs to be a certain color, you can iterate over NUM_LEDS, in the corresponding msgs.

// Set all leds to yellow in right eye
nao_lola_command_msgs::msg::RightEyeLeds right_eye_leds;

std_msgs/ColorRGBA yellow;
yellow.r = 1.0;
yellow.g = 1.0;

for (unsigned i = 0; i < nao_lola_command_msgs::msg::RightEyeLeds::NUM_LEDS; ++i)
{
  right_eye_leds.colors[i] = yellow;
}
