Simulink Support Package for Arduino Hardware enables you to create and run Simulink® models on Arduino board. The target includes a library of Simulink blocks for configuring and accessing Arduino sensors, actuators and communication interfaces.
In this example you will learn how to create Simulink model that controls a standard servo motor. In a standard servo motor, the shaft position can be precisely set, usually between 0 and 180 degrees. Servo motors are used in many industrial, military and consumer applications and products.
