LED Control System Part 7

Part 7: Creating a control system

Modern cars are often equipped with various comfort increasing features. One of these features is the automatic engagement of the lights when it turns dark. On the sensor shield, you’ll find an LDR sensor next tot he potentiometer. This sensor sends out an analog signal that is dependent on the amount of light that’s being picked up by the light sensor.

Use HANtune to read the LDR sensor value and determine at which sensor value you'd want the lights to turn on. Use the knowledge that you’ve gained during the past parts of the tutorial to make the model of the light control system in Simulink. Don’t hesitate to look back at the previous chapters.

Tip: The following function blocks can come to good use and are all available in the Library Browser under Simulink => Commonly Used Blocks.
