| The main aim of the laboratory is to do different experiments with LED light. The user can start with simple PWM controlling of LED. Next, try to keep a constant level of brightness on a bright part of the model. The other aim is to keep the same level of lighting on a dark part of the model, as is on the bright side. | The main aim of the laboratory is to do different experiments with LED light.
